1. AT+i Command Set
1.1. AT+i Command Guidelines
The AT+i commands Internet-mode operations used to control the ETPro Series.
When ETPro Series is in COMMAND mode, basic AT commands and raw data (not
prefixed by AT+i) shall be transparently transferred to the underlying modem DCE
(Digital Communications Equipment), where they will be serviced. AT and AT+i
commands may be issued intermittently. During an Internet session, when ETPro Series
is online, an AT command may be sent to the GPRS/CDMA module using the
AT+iMCM command.
The ASCII ISO 646 character set (CCITT T.50 International Alphabet 5, American
Standard Code for Information Interchange) is used for the issuance of commands and
responses. Only the low-order 7 bits of each character are used for commands or
parameters; the high-order bit is ignored. Upper case characters are equivalent to lower
case characters.
1.2. AT+i Command Format
An AT+i command line is a string of characters sent from a Host to the ETPro Series
while they are in the command state. The command line has a prefix, a body, and a
terminator. Each command must begin with the character sequence AT+i and must be
terminated by a carriage return (<CR>). Commands entered in upper-case or
lower-case are accepted.
Commands that do not begin with the AT+i prefix are transferred to the underlying DCE,
where they are parsed and acted upon. DCE responses are transparently returned to the
host.
The AT+i command body is restricted to printable ASCII characters (032 - 126). The
command terminator is the ASCII <CR> character. The command line interpretation begins
upon receipt of the carriage return character (an exception to this rule are the AT+iEMB,
AT+iSSND and AT+iFSND commands).
ETEK R&D CO.,LTD

..
..
When ECHO. is enabled, the <CR> (Carriage Return) character is echoed as a 2-character
..
sequence: <CR><LF>
(Carriage Return + Line Feed).
..
ETEK R&D CO.,LTD
12
..
..
..
..
.
Characters within the AT+i command line are parsed as commands with associated
parameter values.
The ETPro Series support the editing of command lines by recognizing a backspace
character. When ECHO is enabled, they respond to receipt of a backspace by echoing a
backspace character, a space character, and another backspace. When ECHO is disabled,
backspace characters are treated as data characters without further processing.
If a syntax error is found anywhere in a command line, the remainder of the line will be
ignored and the I/ERROR result code will be returned.
Commands will only be accepted by the ETPro Series once the previous command has
been fully executed, which is normally indicated by the return of an appropriate result
code.
1.3. Escape Code Sequence
While the ETPro Series is in Internet mode, attending to the Internet communications, it is
possible to break into the data communications and abort the Internet mode in an orderly
manner. This is achieved by sending the ETPro Series a sequence of three ASCII ‘+’
characters (‘+++’) after a half second silence period. In response to this, the ETPro Series
will shut down the Internet communications, terminate data transmission to the host and
respond with an ‘I/ERROR(056)’ message and return to command mode. A maximum
delay of 10mSec may still exist from the time the ‘+++’ escape sequence was transmitted
until ETPro Series cuts off the transmission to the host.
The interrupted Internet activity will not be completed, however this will be considered to
comprise a session. Thus, parameters set with the ‘~’ character shall be restored to their
permanent value.
1.4. Auto Baud Rate Detection
The ETPro Series supports auto baud rate detection on the host serial communications
line. After power-up, the ETPro Series will go in to auto baud mode when the BDRF
parameter contains ‘a’.
The AT+iBDRA command forces the ETPro Series into auto baud mode while it is
already in operation.
In auto baud mode, the ETPro Series expects an ‘A’ or ‘a’ character. This is usually the
first character sent, since in Command mode a meaningful command is always prefixed
by ‘AT+i' (or ‘AT’ for ETPro Series). Any other characters shall be discarded without

affecting the..baud rate detection mode.
The host may send an ‘a’ or ‘A’ to the ETPro Series to allow it to determine the host’s baud
rate. It may also send a complete ‘AT+i' (or ‘AT’ for ETPro Series) command. In any case
the ETPro Series will detect the ‘A’ or ‘a’ character, determine the correct baud rate and
configure the ETPro Series’s serial channel during the stop-bit. Thus, the next character
will be received by the serial port at the correct baud rate. The ‘A’ itself is retained as well.
ETPro Series supports auto baud rate detection for baud rates:
2400, 4800, 9600, 19200, 38400, 57600 and 115200.
When the BDRF parameter contains a (fixed) baud rate, the ETPro Series will initialize to
the specified baud rate without entering the auto-baud mode. Commands issued by the
host must be sent using that baud rate in order to be recognized. In this case the ETPro
Series may be forced into auto-baud mode by holding the special input signal low for not
more than five seconds after power-up.
When the BDRM parameter contains an ‘a’ value, the ETPro Series assumes the attached
modem has the auto baud rate feature. Once the host-IP module baud rate is determined
the IP module-GPRS/CDMA module baud rate will be set to the same. Otherwise, any
other value in BDRM will be used as a fixed baud rate to the GPRS/CDMA module.
1.5. Reset via Serial Link
Issuing a ‘BREAK’ signal on the Host serial link will effectively RESET the ETPro
Series. A ‘BREAK’ signal is issued by transmitting a LOW (zero value) for a period
that is longer than 23 bits at the current baud rate. Considerably lowering the host
baud rate (300 baud or less) and transmitting a binary zero will in effect generate a
‘BREAK’ signal. After a ‘BREAK’ signal is issued, ETPro Series requires 4 seconds
to complete the reset cycle before commands may be issued.
When ETPro Series is configured for auto baud rate (AT+iBDRF=a), the ‘BREAK’
method is especially useful to force ETPro Series back into auto baud rate mode when
ETPro Series and the host loose sync.
1.6. Reset via Forced Watchdog Activation (ETPro
315/211 /312 only)
The ETPro 315/211/312 includes an internal Watchdog mechanism. When enabled, the
internal watchdog circuitry will physically RESET the ETPro Series device if the ETPro
Series firmware does not execute in an orderly manner, as expected.
The AT+iWDR command forces the watchdog circuitry to instigate a RESET condition,
as a means to reset the ETPro Series device with an AT+i command from the host.

6.2. +iEMB
.
Syntax: AT+i[!]EMB[#]:<sz >,<data > Define and send a MIME encoded Binary
Email.
Parameters:
<sz > = size of <data > in bytes.
<data > = <sz > bytes of binary data.
Scope: ETPro Series
Command Options: <sz >
= 0..4GB
<data > = 8 bit binary data. Must be exactly <sz > bytes.
The binary data will be encapsulated in a MIME encoded Email
message. The receiving end will view the binary data as a standard
Email attachment.
Several consecutive +iEMB commands may be issued in
sequence to create a larger aggregate of data to be sent.
The Email contents are completed by issuing an AT+iE*
(terminate binary Email) command.
Following the first +iEMB command, ETPro Series will establish
an Internet connection while the data stream is being transmitted
from the host. Once an SMTP session is established, ETPro Series
will maintain a data transmit pipeline between the host and the
SMTP server. ETPro Series converts the binary data using
BASE64 encoding on the fly. Following this command, the
Internet session shall remain active to service additional +iEMB
commands, until the +iE* terminating command.
EMB uses the specified SMTP server to send the Email message.
When ETPro Series acquires TOD from a network timeserver,
outgoing Email messages will be time and date stamped.

Stay On-Line after completing command. This
flag is redundant, as the ETPro Series defaults to
staying online until the AT+iE* command is

I/ERROR
Notes：
Note:
ETEK R&D CO.,LTD
If <sz> is within limits and after <sz> bytes have
been received successfully.
if <sz> is out of bounds, or if a communications
error occurred during the Internet session.
If <sz> is larger than 256 bytes, the ETPro Series
assumes Host flow control. Depending on the
setting of the FLW parameter, the flow control
mode is either software or hardware. Under
software flow control the Host processor must
respond to ETPro’s flow control characters. The
software flow control protocol is detailed in the
“Host IP module Software Flow Control” section
later in this document. When software flow control
is active it is recommended to set the IP module to
Echo-Off mode.
Under hardware flow control the ~CTS/~RTS
RS232 control signals must be connected and the
host must respond to the IP module’s ~CTS signal.
The host may send data only when the ~CTS signal
is asserted (active low). If a transmission error
occurs, while in hardware flow control, IP module

An 8-bit byte stream of exactly size <sz>. If <sz> is
larger than 256 bytes, the ETPro Series assumes Host
flow control. Depending on the setting of the FLW
parameter, the flow control mode is either software or
hardware. Under software flow control mode the
Host processor must respond to the ETPro’s flow
control characters. The flow control protocol is
detailed in the “Host-IP module Software Flow
Control” section later in this document. Under
hardware flow control the ~CTS/~RTS RS232
control signals must be connected and the host must
respond to the ETPro’s ~CTS signal. The host may
send data only when the ~CTS signal is asserted
(active low).

15. IP ..Registration
When ETPro Series goes online, it is normally assigned a dynamic IP address during PPP
establishment. Since a different IP is usually assigned every session, it is not practical to
use the ETPro Series as a server, since the client(s) do not know what IP address to use.
Furthermore, under these restrictions, there is no practical way to know if a specific system
is online or offline.
To overcome this problem, ETPro Series incorporates built-in procedures designed to
register its IP address on a server system, each time it goes online. Once registered, client
systems may interrogate the servers in order to verify the online status of a specific system
and retrieve its currently assigned IP address. The IP registration process is governed by
several AT+i parameters. Once these parameters are configured, ETPro Series will register
its IP address accordingly when it goes online as a result of an explicit AT+i command
(AT+iUP) or as a result of automated Internet session establishment procedures, such as a
triggered Internet session or when going online as a SerialNET mode server.
In cases where the ETPro Series uses a NAT gateway to the Internet, it may be
configured to register the NAT’s IP address and a special port that is linked to the ETPro
Series in the NAT’s configuration. See details in the RRRL parameter description. When
this is the case, the RRRL parameters (IP and port) will be used instead of the local IP
and port values that ETPro Series is assigned, in all registration methods (RRMA, RRSV
and RRWS).
ETPro Series includes several IP registration methods:
15.1.mail Registration
ETPro Series registers itself by sending an Email that contains its ID information
and current IP address.
When the RRMA parameter contains an Email Address, ETPro Series will send
an Email containing its current IP address or its RRRL to the address defined in
RRMA during the registration procedure. The syntax of the Email body is:
<BDY parameter contents>
ETPro-<D/L/S> S/N:<RP5> Version:<RP1> HN:<HSTN> IP:<IPA or RRRL>
Port:<LPRT or 80 or 0> http:// <IPA or RRRL><CR><LF>
The subject line of the Email is:
ETEK R&D CO.,LTD
86
..
..
..
..
"RING RESPONSE
LINK From: ETPro-<D/L/S> S/N:<RP5> Version:<F/W ver>
.
HN:<HSTN> IP:<IPA or RRRL> Port:<LPRT or 80 or 0>"
Where,
Port is LPRT if in SerialNET mode,
80 if not in SerialNET mode and AWS is
enabled, and 0 if not in SerialNET mode
and AWS=0.
The receiving end may refer to the contents of the subject line to filter out this
Email message.
15.2.Socket Registration
ETPro Series registers itself by opening a socket to a registration server and
sending its ID information and current IP address.
When ETPro’s RRSV parameter contains a value, ETPro Series will establish a
socket to the server defined in RRSV, during the registration procedure. When a
socket is established, ETPro Series will transmit its ID information and current IP
address (or the RRRL) in the following format:
“ETPro-<D/L/S> S/N:<RP5> version: <RP1> HN:<HSTN> IP:<IPA or RRRL>
Port:<LPRT or 80 or 0>”
The registration socket is then closed.
15.3.Web Server Registration
ETPro Series registers itself by “surfing” to a Web server with its ID information
and current IP address as parameters.
If the RRWS parameter contains a URL (of a registration Web server) ETPro
Series will register its ID information and IP using the URL, by issuing a GET
command along with a fixed format parameter line:
“<RRWS path>?SN=<RP5>&IP=<IPA or RRRL>&WPt=<0 or the port defined in
RRRL>&HN=<HSTN>”.
The Web server must contain a CGI, .asp page, exe, etc., which will make use
of these parameters to register the ETPro.
If several registration parameters are configured, ETPro Series will go through
multiple registration processes. If more than one registration process fails, ETPro
Series will return an I/ERROR result describing the first failure encountered. If all
registrations fail, ETPro Series will return I/ERROR(90).

17. MIME
Encapsulated Email Messages
17.1.ETPro Series Generated Binary Message Formats
Binary email messages are sent via ETPro Series using one or more AT+iEMB
commands. The message format is limited to an optional body of text and a single
attachment.
The following fields are added by ETPro Series to the main message header:
X-Mailer: ETPro <software version>
Message-ID: < Unique #> @ETPro
Mime-Version: 1.0
Content-Type: multipart/mixed; boundary= ”CONE-ETPro-<software version> ”
The message preamble will contain the following text:
“This MIME message was coded by ETPro. ”
If the host application includes a text body for the message, it will also contain the
following lines in its header:
Content-Type: text/plain;
charset=us-ascii
Content-Transfer-Encoding: 7bit
X-iCoverpage: Email
When no textual body contents are included – this section will be omitted.
The binary attachment section will follow, beginning with a MIME attachment header
containing the following fields:
Content-Type: < User defined media type>/< User defined media
subtype>; name=< User defined attachment filename>
Content-Transfer-Encoding: base64
Where,
<media type>
subtype>
<filename>
ETEK R&D CO.,LTD

..
.. Related AT+i Commands and Parameters
17.2.MIME
.
Binary images are transferred to the ETPro Series for MIME message encapsulation via
one or more AT+iEMB commands. An AT+iEMB command sequence must be
terminated by the AT+iE* command, indicating the end of the binary Email message.
When several consecutive AT+iEMB commands are used, the host must issue the
commands with an inter-command delay, which does not violate the SMTP server’s
timeout constraints. Otherwise, the SMTP server will timeout and abort the session.
Average SMTP servers allow for delays in the range of 30 to 120 seconds. Additional
AT+i commands may be interlaced within a sequence of AT+iEMB commands, except
for The following AT+i commands: AT+iEMA, AT+iRML, AT+iRMH, AT+iRMM,
AT+iRFU, AT+iRLNK, AT+iBDRA and AT+iSNMD.
The ETPro Series does not limit the size of the binary attachment, however, ISP’s might
have limitations. An Internet connection will be initiated immediately after the first
AT+iEMB command, while the rest of the command is received. Once the connection to
the SMTP server has been established, the ETPro Series will act as a pipeline, receiving
binary info from the host, encoding it, and transmitting it to the Internet on the fly.
Following the AT+iE* command, the email will be terminated and the Internet connection
closed.
The Escape sequence command (‘+++’) is allowed within an AT+iEMB command,
provided there is a half second ‘silence’ period before the ‘+++’ is sent. Upon receiving the
escape sequence, the ETPro Series will abort and orderly close the Internet session. The
partial mail message will not be sent to the destination.

18. Flow
18.1.Host ETPro Series Software Flow Control
When issuing an AT+iEMB command to generate a binary Email, an AT+iSSND
command to transfer data to a socket, an AT+iTBSN send a binary stream to a Telnet
server or an AT+iFSND command to transfer a file, the host transfers a binary data
stream to the ETPro Series. At times, this stream may be very large. Once the ETPro
Series establishes a connection, it acts as a pipeline, transferring data received from the
host to the Internet. However, the data rates at the host and Internet ends are not always
balanced. This happens for several reasons:
1. While the ETPro Series is logging on to the Internet and establishing a
connection, the host proceeds to send its data stream to the ETPro Series.
During this time the ETPro Series receives data from the host, but cannot send it
out.
2. When sending MIME attachments the ETPro Series encodes the binary data,
using base64. This inflates binary data roughly in the order of 30%. Thus,
more data needs to be transmitted than is received from the host.
3. When using a TCP/IP socket, the ETPro Series may need to retransmit
packets.
The amount of buffer space available in the ETPro Series to accommodate for this
imbalance is limited. Therefore, a flow control scheme is required to regulate host-IP
module communications. The FLW ETPro Series parameter is set to reflect the preferred
flow control mode.
The software driven, flow control protocol, is defined as follows:
1. While the host is transferring the binary stream, following the +iEMB, +iSSND or
+FSND prefixes, the ETPro Series will issue a ‘WAIT’ control character when it
needs to pause the host. The host application is required to monitor its serial receive
line and pause the transmission when a ‘WAIT’ control character is received.
2. To resume the host transmission the ETPro Series will issue a ‘CONTINUE’
control character. The host is required to monitor its receive line after being
paused in anticipation of this control character. Once received the host may
continue to transfer the data stream.
3. If an error occurs during the Internet session, while the host is transferring the data
stream (or while paused), the ETPro Series will issue an ‘ERROR’ control character,
if some error occurred. Immediately after issuing this control character, the ETPro
Series will abort the Internet session and issue an ‘I/ERROR (error number)’ string.

18.3.Software
Flow Control During a Socket Send
.
When a ‘WAIT’ control is sent to the host during a socket send (AT+iSSND) command, it
is automatically followed by a RP4 socket status in the following syntax:
I/(<sock0sz>, <sock1sz>, … ,<sock9sz>)<CR/LF>
See the AT+iRP command for a full description.
While the host is waiting for the ‘CONTINUE’ control, it may analyze the sockets’ input
buffer status. If the host detects a need to execute a socket receive command to empty one or
more socket input buffers, it may escape the current SSND command by issuing a ‘Pause’
sequence immediately after receiving the ‘CONTINUE’ control. The ‘Pause’ sequence is
defined as: ½ second of silence followed by ‘---‘ (three consecutive minussign characters).
The ETPro Series will respond by prematurely terminating the SSND command, including
flushing the current socket if the ‘%’ flag was specified. Following this, the ‘I/OK’ will be
issued and the host may issue the required SRCV command in addition to any other
operations it needs to execute. The host may return to the preempted socket at any time and
issue a new SSND command to send out the balance of data.

18.5.Host-IP
module Hardware Flow Control
.
As an alternative to the software flow control method, which requires some software
attention on behalf of the host, the ETPro Series offers a hardware flow control mode.
This mode is selected be setting the ETPro’s FLW parameter Bit 0, using the AT+iFLW
command. Note that to set FLW Bit 0, the ~CTSH signal needs to be LOW (Enabled),
otherwise ETPro will return I/ERROR(063). This convention safeguards the ETPro Series
from lockup, which may arise if FLW Bit 0 is set while the ~CTSH signal is constantly
HIGH.
For hardware flow control to operate properly, the ~CTS and ~RTS signals between the
host and IPmodule UARTS must be inter-connected.
The IP module ~CTSH and ~RTSH may be shorted to circumvent H/W flow control.
Under this mode the ETPro Series will assume that the host transmission may be paused by
de-asserting the ~CTS signal. The host must adhere to this convention. Most UARTs
support hardware flow control, however if this is not the case, the ETPro’s ~CTS signal
should be monitored by the host software on a general-purpose I/O.
The host may also pause the ETPro Series by de-asserting its ~CTS signal.
If a transmission error occurs during processing of a send command (EMB, SSND,
TBSN, FSND), the ETPro Series shall accept all remaining characters pertaining to the
current command (as specified by the <sz> parameter) before returning the relevant
I/ERROR response.

19. ETPro
Series Email Firmware Update
19.1.Introduction
The ETPro Series accepts firmware updates in a variety of methods, each appropriate for a
different situation. The ETPro Series accept Ymodem uploads directly to their serial ports.
A Ymodem server (such as HyperTerminal on a PC) may be used to download a firmware
image file over a serial cable from one of the PC serial ports. This method is convenient
when downloading firmware updates to a local ETPro Series. Ymodem based updates may
also be downloaded over a direct (PSTN) phone line to a ETPro Series(ETPro 211/312/315
only) connected to a dial-up modem. This method is effective when downloading firmware
updates from a remote location or when the ETPro(ETPro 211/312/315 only)’s serial port is
not accessible. ETPro Series firmware may also be uploaded using a Web browser through
the internal configuration Web site. This is convenient when the ETPro is online and its IP
address is known.
In addition to the Ymodem and Web based firmware update methods, the ETPro Series
accept remote firmware updates administered by Email.
The firmware update is sent as an Email attachment, which is downloaded by the ETPro
through a POP3 session. The ETPro automatically recognizes a Firmware update Email
and acts upon it by replacing its existing firmware with the new one through a bootloader
encapsulated in its boot block. This method is especially convenient when managing
firmware updates in a globally distributed install base of Internet enabled devices. The
ETPro Series provides several methodologies to govern Email based firmware updates,
designed to allow the system architect a multitude of configurations which best suit the
system’s needs.
19.2.Transparent Update
According to this methodology, the ETPro Series accepts firmware update attachments
while normally downloading Email messages from its POP3 account. When the ETPro
Series encounters a firmware update attachment, while executing an AT+iRMM command
to retrieve Email messages, it defers the firmware update attachment file to its internal
boot loader rather than transferring the attachment contents to the host.
Regardless of the position of the firmware update attachment in the POP3 mailbox, the
ETPro Series processes the firmware attachment last, after transferring all the other
ETEK R&D CO.,LTD
102
..
..
messages to .the host in the normal manner. Since the update process may take as long as 4
.. Series issues the “I/UPDATE’ message to notify the host that it is
minutes, the ETPro
..
updating its firmware.
The host must allow for an extended delay period until the ETPro
Series completes the update process. Once complete the ETPro will reboot the new
firmware and issue the ‘I/DONE’ message to the host. In this case the ETPro will be
offline, even if the stay online flag was set in the RMM command (AT+i!RMM).
The firmware attachment shall remain in the mailbox even if the ‘Leave on Server’ flag is set
to ‘NO’ (0). However, the ETPro Series will not attempt to download it again when
executing the next AT+iRMM command, as it is aware that the current firmware has
already been updated. This is useful if more than one ETPro Series controller share the
same POP3 mailbox or when the update process has failed and needs to be attempted again
during the next Email retrieve session.
Several safe guards have been instated in order to assure a successful firmware update. The
firmware attachment is structured by ETEK in a specific format, which allows the ETPro
Series to authenticate its origin as a legal firmware image. The ETPro Series will also
verify that the firmware update is the correct version for its hardware environment. As
mentioned above, ETPro Series will also reject an email firmware update if it contains an
identical image to the one already existing in the specific ETPro controller. Further more,
the attachment is encoded and cross-check-summed to allow the ETPro Series to verify that
its data contents are intact after being downloaded and as a precaution against corrupted
firmware attachments and malicious firmware update attacks (such as viruses). If a
firmware update Email was downloaded but did not eventually replace the original
firmware as a result of a checksum error, an I/ERROR(113) message will be sent to host.
Nevertheless, if under rare and extreme situations the firmware update does not succeed
after the original firmware was erased from the ETPro’s flash memory, the ETPro Series
will automatically enter Ymodem update mode to allow an alternative firmware update
route. If this situation ever happens, manual attention is needed.
19.3.Initiated Update
System designers may prefer to disable the transparent update mode as an additional
precaution and in order to gain better control over the update process. Transparent update
mode is governed by the UEN (Update ENabled) flag. This flag may be set to 0 (Disable
firmware updates) or 1 (Enable firmware updates), using:
AT+iUEN=<value>
When the UEN flag is 0 (disabled), AT+iRMM commands will skip firmware update
attachments encountered during an Email retrieve session. In this case, a firmware update
may be initiated using a dedicated command:
AT+iRFU (Remote Firmware Update)

103
..
..
After the host. issues this command, the ETPro Series will execute an Email retrieve session

.
skipped. If a .firmware attachment is found, the update process proceeds as described in the
transparent update case. If more than one firmware attachment resides in the mailbox, only
the last one will be considered.
The advantages of this methodology are to allow external events governed by the host to
determine when and if to proceed with a firmware update. These events may be a timeschedule, a keystroke sequence applied to the host system, a message sent to the host via
Email or through a dedicated TCP/IP socket, etc.
19.4.Dedicated Mailbox Update
In some situations it may be preferred to direct the ETPro Series to a dedicated mailbox
for firmware updates. Three additional parameters are dedicated for this purpose:
AT+iUMBX=<Update Mailbox Account Name>
AT+iUPOP=<Update Mailbox POP3 Server>
AT+iUMPW=<Update Mailbox Password>
When these parameters are set, the ETPro Series will scan the UMBX mail account when
responding to an initiated AT+iRFU command. Only firmware update attachments shall be
downloaded. Other mail messages shall be skipped. Only the UMBX parameter is required
to be set, while UPOP and UMPW may be left empty, in which case the POP3 and MPWD
parameters will be used.
This methodology is especially useful when setting up a common firmware update mail
account, to be shared by many ETPro units. ETPro controllers may each have their own
mail account for normal operation using the AT+iRMM command. However, when
initiating a firmware update all units retrieve mail from the same account, specifically setup
to support firmware updates for all units. A central management headquarters can issue the
firmware attachment, once, to the dedicated mailbox rather than sending individual mail
attachments to each unit’s mailbox. This also relieves the requirement to maintain a
database of mailboxes used by the devices.
In addition, groups may be formed to access different update mailbox accounts. For
example, systems incorporating the ETPro may access one update mailbox, while another
ETPro units access another. This configuration will achieve better performance, since
ETPro Series controllers will not need to reject the others firmware update, as is the case if
they were all to share the same update mailbox. Of course other grouping schemes may be
warranted by specific implementations.

Update Distribution

.
ETEK shall distribute Email firmware attachments “ready to go”. The Email attachments
will be sent to ETEK’s distributors, VARs, OEM’s and direct customers using normal
Emailing procedures. The Email attachments may be picked up with any standard Email
application. In order to apply the firmware update the Email attachments may be
forwarded, as is, directly from any Email application to the destination mail account,
depending on the methodology used by the recipient ETPro Series controller.

20. ETPro
Series Parameter Update
20.1.General
The update file allows a user to remotely modify various nonvolatile parameters in
ETPro Series.
The file is an ASCII formatted text file, edited by the user or created by a dedicated
application. The file’s size should not exceed 10k.
The remote parameter file (RPF) naming convention: <filename>.rpf
If a parameter is assigned with a legal value within the file, that value will replace
the current value in the ETPro Series nonvolatile parameter database. A parameter
value which is not referred to in the file, or which is not defined using the correct
syntax rules, specified below, will not affect the current parameter value.
20.2.Remote Parameter File (RPF) Structure
The file must include the letters “RP_” as its first 3 characters, and can include
additional header lines (defined below) as well as various parameter assignments.
Assignments will follow the rules and definitions defined for parameter settings
using AT+i commands, excluding the AT+i prefix. For example – to assign the
value “myname” to the POP3 mailbox name parameter, the correct assignment is
“MBX=myname” (identical to the host sending the “AT+iMBX=myname” to the
ETPro).
Each line (terminated with CR/LF) may contain only one assignment.
Order of assignments is not essential except for the RPF header parameters which must
be first, and must follow the header definitions below. After the first non RPF header
parameter additional header parameters are ignored.
Comment lines can appear anywhere in the file. Comment line syntax is defined as:
#<anything>CR/LF
The first line in the file which is not a comment line is considered the authentication
header line and must follow the following syntax:
RP_[GROUP=<string><space character>][RP_DEST=<string>]CR/LF
ETEK R&D CO.,LTD
106
..

RP_GROUP – if the RPF Group Name parameter in the ETPro
Series contains a value, the RPF file must include an
RP_GROUP definition and its value must be identical to the
RPF value, otherwise the parameter update file will be rejected.
Nevertheless, if the RPF parameter is set to the special value ‘*’
(match any), the RPF file shall be accepted with any value of
RP_GROUP, as well as without any value at all. The RPF
Group Name parameter can be viewed and changed by sending
an ‘AT+iRPG?’ command to the ETPro.
•
RP_DEST – if the RPF file contains this parameter, the
parameter update file will be rejected unless the value given in
this parameter is identical to the unique ID of the ETPro Series
it was sent to. The unique ID can be viewed by sending an
‘AT+iRP5’ command to the ETPro, but cannot be changed. This
feature facilitates sending a parameter update to a specific
ETPro Series controller only.
•
RP_ START_FROM_FACTORY_DEFAULTS – This
flag defines the initial value of parameters. A value ‘YES’ will initially restore all ETPro Series parameters to their
factory default values before processing the new RPF file
values.

20.4.Uploading
a Parameters Update File to the ETPro
.
Series
By default, receiving and processing a parameters update file is disabled in the
ETPro Series. To enable this option, the RPG parameter must be set to some value.
If a value other than “*” is set, the value must match the parameters update file
RP_GROUP value. This feature facilitates group updates, or can be used as a
password to secure parameter updates.
A remote parameters update file can be uploaded to the ETPro Series using the
same methods available for upload a firmware update:
1. Via Ymodem Protocol:
Remote modem connection,
Local modem connection, or
Serial connection.
The Ymodem update process is evoked by issuing the AT+iPU command
2. Via Email:
While processing an AT+iRMM command.
The nonvolatile parameter RPG controls the parameter update. If it does not
contain a value, the update process is effectively disabled. If it contains an
‘*’ it is fully enabled. If it contains a value, the update process is restricted to
RPF files containing that value in the RP_GROUP header parameter.
3. Via the Web:
Through the ETPro’s internal configuration site. See description
in following chapter.
To upload a parameter update file via Email send an RPF file Email to the mailbox
defined in the ETPro Series. The Email must consist of a single plain text
attachment of the RPF file, or the RPF file contents can be copied and pasted into
the Email body itself.
The Email massage’s subject field must include the special string
“IC_Parameters_Update”.
When ETPro Series retrieves an RPF file, during an AT+iRMM session, the
contents of the Email message will not be sent to the host. The parameter update

21. ETPro
Series Embedded Web Server
21.1.Introduction
The ETPro Series includes a full-blown Web-server that handles HTTP 1.0/1.1 Web
interactions independently of its host processor. It allows system designers to build Webbased products, which can be remotely monitored, configured, and managed via the
Internet using a standard Web browser interface.
The ETPro Series devices host two on-chip Websites, stored in on-chip nonvolatile
memory. One Web site is inherent to the ETPro firmware and is dedicated to ETPro
configuration and maintenance. The second site is uploaded to the ETPro for device
application use. This Website may include multiple linked HTML pages, links to external
pages, images, graphics, Java applets, WAP pages, etc. A special facility allows the Web
pages to include references to the embedded application’s variables.
The ETPro’s embedded Web server is designed to integrate with the existing IP
module-to-Host API methodology, based on AT+i command interface.
21.2.Features
Responds to standard Web browser “GET” and “POST” commands issued to
port 80.
Supports up to three concurrent remote browsers simultaneously.
Serves on-chip HTML pages stored in ETPro’s nonvolatile memory.
May incorporate WAP pages to allow browsing the ETPro Website using an
Internet-enabled cellular handset.
The internal ETPro-configuration Website supports remote ETPro parameter
configuration, remote ETPro firmware upload, and remote application-Website
upload. All the above are achieved using a standard Web browser. Configuration
access is protected with an MD5-encrypted password mechanism.
Support for monitoring and controlling the host device using a pre-defined set of
parameters embedded within the application-Website (also MD5 password
protected).
Integrates seamlessly with the existing AT+i methodology.

.. Server Modes
21.3.Web
.
Two Web server modes are defined as (see Fig. 21.1):
♦
♦
ETPro configuration mode
Host interaction mode
Each of the modes is supported by a dedicated Website and a parameter access password.
The ETPro configuration mode allows remote ETPro Series configuration. It
encompasses Web interactions between the ETPro Series and a remote browser to
carry out ETPro parameter maintenance and ETPro firmware and application Website
uploads. The host processor does not take part in the interactions under this mode.
Moreover, the host processor presence is not required at all for this mode to operate.
Once an ETPro Series is on-line and in possession of an IP address, any remote
browser may “surf” to the ETPro and update its nonvolatile parameters without the
host’s involvement. The ETPro configuration site is located at: HTTP://<ETPro IP
Address>/ETPro/.
In Host interaction mode, ETPro is used to host, serve and manage Web interactions
with a remote Web browser, on behalf of the embedded device’s host processor. The
host gains access to the Web-based parameters via AT+i commands sent to ETPro
through the serial connection.
Figure 21-1: ETPro Web Server Modes
21.4.The Application Website
The application Website is stored in ETPro. It consists of normal ASCII text HTML
code, which may include additional links to locale or remote Web pages, graphic
images, text files, Java Applets, WAP pages, etc.
Device manufacturers may design their own embedded-Website using any typical

ETEK R&D CO.,LTD
114
..
..
..
..
21.5.Parameter
Tags
.
ETPro and host real-time parameters may be referred to in the embedded Websites through
the use of “Parameter Tags”. When Parameter Tags are placed in an HTML Web page,
actual values are sent by the ETPro’s Web server component when the page is served out.
Parameter Tags are also used to change corresponding parameter values from a remote
Web browser.
Syntactically, Parameter Tags are parameter names enclosed between two ‘~’ characters. If
the ‘~’ character needs to be included in a Web page, two consecutive ‘~’ characters must be
used (‘~~’).
The ETPro Series Internet-configuration parameters, defined in the AT+i API, retain their
name when used as Parameter Tags. For example, the value of the TOA AT+i parameter
(“Send to” Email Address) may be referenced in the Website by ~TOA~.
Host Parameter Tags defined by the parameter name <param>, may be referenced in the
Website using ~<param>~. <param> may be any freeform parameter name, consisting of a
single word, which does not include blanks or ETPro delimiters. For example, a parameter
reflecting a temperature reading may be called temperature and referenced in the Website as
~temperature~.
21.6.ETPro Configuration Mode
ETPro configuration entails monitoring and updating ETPro parameter values. By making
use of the ETPro’s inherent configuration Website, an ETPro Series device may be
configured remotely using a standard Web browser, in addition to being configurable
locally by use of the Ymodem protocol over the serial link, via Email. The ETPro Series
RPG parameter is used to password protect remote ETPro parameter updates. See
Security and Restrictions.
The configuration site includes Web forms to monitor and update most ETPro parameters
and an upload page, consisting of file upload forms. Each upload form allows file
uploading using the POST method for a single file.
The forms support uploading the following files:
1. Firmware update *.imz file
2. Parameters update *.rpf file
3. Packed application Website *.img file
When new firmware (*.imz file) is uploaded to ETPro, the ETPro will submit an
acknowledgment page to the browser, after receiving the complete *.imz file and will
then go offline and update its firmware.

.. Interaction Mode
21.7.Host
.
Host interaction mode allows OEMs to design and implement a product-related embedded
Website that is managed by ETPro on behalf of the host. The host-defined embedded
Website supports live host parameter monitoring/update by a remote browser. This is
achieved by a dynamic AT+i layer implemented across the serial link between the host and
the ETPro Series.
The application developer defines a Website using conventional Web authoring tools. The
HTML\WAP files may then be edited to contain “Parameter Tags”. Parameter tags are
regarded as placeholders in HTML\WAP files that are replaced on the fly with real-time
values as the page is served to the browser. Browsers may also change values of Parameter
Tags in order to submit the value back to the host via ETPro. This is done by defining the
Parameter Tag in the NAME field in an HTML FORM (without the ‘~’ characters). The
ETPro Series WPWD parameter is used to password protect remote Parameter Tags update.
See Security and Restrictions.
Once a Website is created and Parameter Tags are edited in, the site is packed and uploaded
to ETPro. The Web site is linked into the ETPro Series firmware, automatically expanding
the existing AT+i command set to encompass the Website Parameter Tags, once the Web
server is activated with the +iWWW command.
Extended AT+i commands have the syntax:
AT+i<param> = <value> and,
AT+i<param>?
to set and query Parameter Tag values respectively.
For example, Parameter Tag ~temperature~, referenced in a Web page, may be set using:
AT+itemperature=’45 Deg.’
and queried using:
AT+itemperature?.
When the host issues a Parameter Tag set-value command, the ETPro Series links the
updated value to the Parameter Tag and stores it in its internal RAM. In response to a
browser’s GET request, the real value is substituted while the page is being served, on the fly,
anywhere in the page where the Parameter Tag exists.
Parameter Tag values are always printable ASCII text. This convention allows
implementing any part of an HTML\WAP page as a parameter tag: numeric values, links,
file names, HTML code, etc. A Parameter Tag value is limited to 256 characters.
Parameter Tag values may be changed and submitted from the browser end, using HTML
forms. ETPro stores the updated values and responds appropriately to host AT+i query
parameter commands. Thus, the host can poll specific parameters for value changes. Status
Report 7 (AT+iRP7) may be used to facilitate polling on all application Web parameters.

21.8.Website
Creation, Packing and Uploading
.
Device manufacturers may design their own embedded Web site using any typical Web
authoring tool. A Website may include one or more files residing in a dedicated file
directory structure on the designer’s PC. The topmost directory of this structure is referred
to as the Website root directory. The root directory must contain an HTML page named
“index.htm”, which will be served as the default home page.
Before downloading the Website to an ETPro device, the entire Website needs to be packed.
In order to pack the site into an uploadable image file, the designer must run ETEK’s Web
packing utility, and specify the root directory of the site. The utility will pack all files in the
root directory and its subfolders, in a format that can be uploaded to the ETPro. If the site
contains Parameter Tags, the user will be prompted to enter a maximum value length for
each Parameter Tag. Any Parameter Tag specified with a zero length value will not be
included in the resulting packed file. After the user has entered all parameters’ max value
length, the user will be prompted to specify a destination file for the packed file.
The following restrictions apply when creating the packed Website:
1.
The length of a single Parameter tag must not exceed 256 characters.
2.
The sum of all Parameter Tags’ value lengths must not exceed 8k.
3.
The total packed file must not exceed 32k.
To take affect the packed Website file needs to be uploaded to ETPro. This may be
achieved by issuing the AT+iPU command and sending the file via Ymodem over a
local serial link or by uploading the packed file through the ETPro’s configuration
Website over the Internet.
21.9.Manipulating Variables in the Application Website
The application Website is composed of HTML\WAP files, which may contain links to
internal or external Web sites, Java Scripts, VB scripts, graphic files, etc (See list of
supported file types). Using Parameter Tags, the page can also be used to dynamically
display and update values of ETPro’s configuration parameters and/or device specific
Parameter Tags in the manner described above.
For example, to display the current value of the Web parameter headline, write
“~headline ~” anywhere in the page, as in the following example:
<HTML>
<HEAD>
<TITLE>SAMPLE PAGE</TITLE>
</HEAD> <BODY>
<h1>~headline ~</h1>
</BODY>
ETEK R&D CO.,LTD
120
..
..
</HTML> .
..
.
When serving. this home page, ETPro’s Web server will replace the
“~headline ~”
ETEK R&D CO.,LTD
121
..
..
..
.. page, on the fly, with the actual current value of that parameter in
string in the served
.
ETPro.
For example, if the host issues:
AT+iheadline=”Hello world”
a browser pointing to the ETPro’s URL address
will display the image as seen on the right.
To update the ETPro Series configuration
parameter via the Web page, simply use
ETPro’s parameters names (excluding the
“AT+i” prefix) in an HTML form.
For example:
<HTML>
<HEAD>
<TITLE>SAMPLE PAGE</TITLE>
</HEAD>
<BODY>
<FORM METHOD=’GET’ ACTION=’’>
Dial To:<INPUT type=’text’name=’ISP1’value=’~ISP1~’>
<input type='submit' size='8' value='Submit'>
</FORM>
</BODY>
</HTML>
Note that the variable name is used in the NAME field, while ~<parameter name >~ is
used to display the current value.
After activating ‘SUBMIT’, the browser will issue a GET command to the ETPro Web
server that includes the parameter’s name and the new value entered in the form. The
page will then be served to the browser again with the updated values.
In addition to specifying ETPro Series configuration parameters and Parameter Tags, it is
also possible to display ETPro reports (RP0-RP5). For example:
<table>
<tr>
<td width=250><b>MAC Address: ~MACA~ <b></td>
</tr>
<tr>
<td width=250><b>Bootblock Version: BBIC~RP3~</b> </td>
<td width=400><b>Firmware Version: ~RP1~</b></td>

<td width=400><b>Hardware Version: ~RP0~</b></td>
</tr>
</table>
ETEK R&D CO.,LTD

..
..
..
21.10. .. Security and Restrictions
.
The authority to update ETPro Series’s configuration parameters, firmware or application
Website via the Web may be password-restricted using the AT+iRPG parameter (Remote
Parameter Group/Password).
When the RPG parameter in an ETPro Series device contains a value, it is considered a
password that restricts remote ETPro parameter updates. To enable remote updates, a
distant user must be authenticated by submitting that value. The ETPro configuration site
includes an authentication form that automatically pops up on the remote browser when
parameter updates are attempted. The password submitted through this form must match the
actual value of ETPro’s local RPG parameter. Otherwise, remote value updates shall be
rejected.
ETPro uses the industry standard MD5 algorithm to authenticate the remote user.
According to MD5, the actual password, typed in to the authentication form, is not
literally communicated back the ETPro. Rather, an (MD5) encrypted token is transferred
instead. To achieve this, the ETPro Web server sends a JavaScript, which calculates MD5
encryption at the browser end, along with the authentication form. ETPro also issues a
different random number, used as part of the encryption key, each time authentication is
required, to eliminate the possibility of impersonation based on eavesdropping to a legal
authentication session. The MD5 algorithm is documented in RFC 1321.
If the RPG parameter is empty (AT+iRPG=‘’), remote ETPro configuration parameter
update is fully restricted. In other words, it will not be possible to update configuration
parameter values using a remote browser. Conversely, if the RPG parameter contains an ‘*’
(match any), the configuration parameters may be updated freely, without requiring
authentication at all.
The Parameter Tags defined in the application Website are secured for remote updates in the
same manner as the ETPro configuration parameters. In this case the authentication
password is stored in the ETPro’s local parameter ‘WPWD’ (Web Password). If the
WPWD parameter contains a value, a remote user needs to issue this value as an
authentication password in order to gain update access to the application level Parameter
Tags. Like in the case of the RPG parameter, if WPWD is empty, application level
Parameter Tags are fully restricted, while when WPWD contains an ‘*’, updates are
unrestricted and authentication is not required.
When authentication is required, the ETPro Web server will automatically issue an
authentication form to the remote browser in response to an attempt to update Parameter
Tags. This procedure allows the application site to include HTML submit instances
anywhere in the Web site without worrying about the authentication process.
Authentication will be automatically activated depending on the local value of the local

22. ETPro
RAS Server
22.1.Introduction
The ETPro feature an internal RAS server, which makes it possible to dial in to these
devices, using an active modem platform. This feature allows a remote dialer to dial in
to the ETPro and, when configured as a RAS (Remote Access Server), ETPro will
answer the call and negotiate a PPP connection.
ETPro’s RAS supports acknowledging an IP address request from the remote dialer side as
well as assigning a default IP address. Once the connection is established the client will be
able to browse ETPro's Web site (if the AWS parameter is set to a non-zero value). All
other ETPro IP protocol functionality will be enabled as well, allowing the host to issue
Internet protocol AT+i commands based on the PPP connection. Note, however, that since
ETPro is not connected to an actual ISP in this mode, ETPro will not have access to the
public Internet and thus only direct connections between the ETPro and the connected PPP
client will be possible.
22.2.RAS Parameters
Three parameters govern the use of ETPro’s RAS server:
i.
RAU
- RAS Login User Name
The RAU parameter defines the allowable user name for login
purposes, when ETPro answers an incoming call as a RAS. The
remote dialer must specify the correct user name and matching
password in order to successfully complete the PPP connection.
This parameter must have a non-empty value for the RAS
feature to be enabled. Otherwise, when RAU is empty the
ETPro ’s RAS is efectively disabled.
When RAU contains the special character, ‘* ’, the RAS is
enabled but no authentication is required.
ii.
RAP
- RAS Login Password
The remote dialer must provide the correct password in order to
successfully complete the PPP connection. When the RAP
parameter is empty or contains, ‘* ’, any password string will be
accepted, in efect nullifying the authentication process.
iii.
RAR
- Number of RINGs before picking up the line
When ETPro’s RAS feature is enabled, the RAR parameter

defines the number of RINGs that must arrive before ETPro
picks up the line and transfers control to its RAS.
128
..
..
..
.. Theory of operation
22.3.RAS
.
When a remote client dials in to the ETPro, the modem RING strings are transferred by
ETPro (which defaults to transparent mode) to the host. When the RAS feature is enabled
(RAU contains a value), ETPro will pick up the line and negotiate a PPP connection, by
issuing the ATA (modem) command after RAR RING strings have been received. If the
host chooses to manage a direct (modem-to-modem) data connection, it may pick up the
line before RAR ‘RING’ strings have arrived, by issuing the ‘ATA’ modem command.
During RAS PPP negotiations, ETPro will reply only to ‘+++’ (Escape sequence) and
AT+iRPn commands. Specifically, ETPro will reply “Connecting as RAS” to the
AT+iRP2 (ETPro Status) command. The Escape sequence may be used to abort the RAS
session at any time. The AT+iRP2 command is the only means for the host processor to
determine that a PPP session is in progress. ETPro manages the RAS protocol internally
and does not transfer any information to the host. Any other commands that may be
received from the host will be disregarded by ETPro.
Once the PPP connection has been fully negotiated and established, ETPro will respond to
all AT+i commands as when it is on-line. Specifically, ETPro will reply “RAS Connected” to
the AT+iRP2 command.
As part of the PPP negotiation ETPro will assign itself the default IP 192.168.0.1 and
allocate 192.168.0.2 as the client IP. However, if the client requests a specific IP, ETPro
will always grant the client’s request and use the client’s IP minus 1 as its own IP. The
following restriction to the minus 1 rule will apply: if the IP requested by the client minus 1
is an IP address that ends with 0x00 or 0x255 as the last nibble, ETPro will assign itself with
the client’s IP plus 1 instead of minus 1. This is done to assure that the IP ETPro assigns
itself will never violate the rule that defines that a network or host IP segment may not be
all binary 1's, nor all binary 0’s.
After a RAS PPP connection is established, ETPro will automatically activate the internal
WEB server, if the AWS parameter is set to a non-zero value. Thus, the remote client may
browse the ETPro’s Web site.
ETEK R&D CO.,LTD

..
..
..
Auto PPP.. RAS Mode
.
ETPro allows combining RAS and direct modem-to-modem communication sessions. A
special mode, named Auto PPP RAS, supports dialing in to the ETPro with a PPP dialer or a
regular modem.
Auto PPP RAS mode is enabled by enabling RAS mode and adding a +100 offset to the
RAR parameter, where [<RAR >-100] determines the number of RINGS after which ETPro
will automatically pickup the line and negotiate a PPP connection.
The host processor may instruct the modem to pick up the line beforehand, by issuing the
ATA (modem) command or by setting the modem to auto-answer after less than
[<RAR >-100] RING strings. This is normally done in order to manage a direct
modem-to-modem (non PPP) communication session.
When ETPro is in the Auto PPP RAS mode, it will monitor the data stream following the
modem “CONNECT” line. If the first character transmitted by the remote end is ‘~’ (0x7E),
ETPro will defer to PPP negotiation. The ‘~’ will be the last character transmitted to the host
end to signal that ETPro has taken over the negotiations. Upon this event, ETPro will
continue to negotiate a PPP connection internally in a manner similar to the procedure that
occurs when ETPro picks up the line after receiving <RAR > ‘RING’ strings. If, however,
the first character received from the calling end after the “CONNECT” line is not a ‘~’
(0x7E), ETPro will remain in Transparent mode, and a regular modem-to-modem data
session will transpire.

..
.. Mode
SerialNET
.
The RAS may also be enabled while ETPro is in SerialNet mode. In this case, however,
the modem ‘RING’ strings will not be forwarded to the host serial port. Once the PPP
connection is established, ETPro will proceed to act as it would after receiving a RING
event and creating a PPP connection to a remote RAS server. That is, a listen socket will
be established on the LPRT socket, available for a SerialNET connection. This provides an
alternative means to ‘wake-up’ a SerialNET server device.

Lost Carrier
.
When ETPro is online as a result of a RAS connection and the Carrier signal is lost (due to
an error or due to the PPP client closing the connection) ETPro will check if during the
connection the host used the PPP connection (tried to open an internet session). If the host
did not use the connection or ETPro was in SerialNET mode, ETPro will silently perform a
software reset and no indication of the disconnection will be given to the host. Otherwise, if
the host did use the connection, ETPro will act as if this was a regular session created by the
host that was terminated with a lost Carrier signal (the error code will be returned to the
host on the next command that requires the use of the connection and only then will a
software reset be performed).

Modem ‘RING’ strings will not be detected while the baud rate between ETPro and the host
is not yet established. This means that in order to use the RAS feature one of following
must apply:
1. BDRF was set to a fixed value (3-9).
2.
ETPro is in SerialNET mode with its baud rate defined by the SNSI
parameter.
3.
An ‘a’ or ‘A’ was previously received from the host serial port and ETPro
has determined the host’s baud rate.

23. SerialNET
Theory of Operation
23.1.Introduction
ETPro SerialNET mode extends a local asynchronous serial link to a TCP or UDP socket
across Internet. Its main purpose is to allow simple devices, which normally interact over a
serial line, to interact in a similar fashion across a network, without requiring any changes
in the device itself. In order to achieve this, SerialNET mode defines a set of associated
operational parameters, which define the nature of the desired network connection. When
ETPro is put in SerialNET mode it acts as a router between the device’s serial port and the
network.
Devices that communicate with a terminal over a serial link fall into three major categories:
Output only (i.e. printers), Input only (i.e. controllers) and interactive (bidirectional
communications). The latter are subdivided further into clients and servers. Generally,
clients initiate communications by sending service demands to a server, while servers
respond to client demands.
SerialNET mode reacts differently to client or server devices. When a client device
initiates communications, SerialNET mode must establish a network connection to a
remote server before data may flow between the two systems. On the other hand, when a
remote client needs to invoke a device, the remote client first contacts the ETPro and
SerialNET is invoked to create a communication flow to the local server device.
SerialNET mode in ETPro includes components to handle both server and client local
devices. The ETPro under SerialNET mode will route full-duplex data between a
networked terminal and both types of devices.
23.2.SerialNET Mode
ETPro's SerialNET mode is established by first defining all related parameters using AT+i
commands, followed by a special “Enter SerialNET Mode” AT+i command.
Once in SerialNET mode, no additional AT+i commands may be sent, as the host serial
link will be dedicated to raw local-device data. In this mode, auto baud rate is also disabled,
since it cannot be guaranteed that the device will issue an ‘a’ or ‘A’ as its first character.
Thus, a predefined fixed baud rate must be specified before switching over to SerialNET

mode.
..
. will extend across power down, since it is assumed that once acting in
SerialNET mode
this mode, ETPro will not normally be connected to an AT+i aware host.
SerialNET mode may be terminated by:
issuing the ESC sequence defined as <half second Delay> followed by “+++” (3 ‘+’
characters) through the serial port; When one of these occur, the ETPro shall reboot after
terminating SerialNET mode. At this point the ETPro reverts to its normal operational mode
and again responds to AT+i commands.

..
.. Devices
23.3.Server
.
Server devices linger until approached by a remote client. The remote client must know
the ETPro’s IP and Listen port address in order to establish communications.
A ETPro is normally off-line and must thus be awakened to go online at a precise moment.
Moreover, once it connects to the Internet it usually receives a dynamic IP address. This
address must be communicated in some way to the client device in-order to establish a link
across the Internet. ETPro resolves these problems by supporting a wakeup call and
automatically implementing one or more IP registration procedures. This allows a client to
wake-up an ETPro in SerialNET mode and retrieve its dynamic IP address from a
registration server.
A ETPro is offline by default, but waits for a ‘RING’ signal on the modem to trigger it into
activity. In this case the remote client device dials directly to the ETPro and hangs up
after 2 rings. When contacted, the ETPro (under SerialNET mode) waits for the ‘RING’
to subside and then dials in to its ISP and connects to the Internet. If the RRMA
parameter contains an Email Address, ETPro will register its IP address using the Email
registration method. ETPro will then listen on the LPRT port for a socket connection. The
recipient of the Email may use the registered IP address and Port to create a link to the
ETPro’s SerialNET socket.
If the RRSV parameter contains a server-name and port, ETPro will register its IP address
using the Socket registration method.
If the RRWS parameter contains a URL, ETPro will register its IP address using the Web
server registration method.
Once connected, the ETPro transfers all arriving data from the local device over the serial
link. Device responses are routed back to the initiating client. Data will flow freely between
the two systems until a predefined activity termination event is triggered, upon which the
remote connection is dropped.
23.4.Client Devices
Client devices initiate communications to a server. When a client device first sends data
on its serial link, the ETPro (in SerialNET mode) buffers the incoming data bytes and
attempts to establish a connection to a remote server. After going online, ETPro will
perform an IP registration process, according to the RRSV, RRWS and RRMA
parameters.

period. The MBTB parameter dictates the maximum number of bytes
.
to buffer. If additional bytes are received on the serial port before the connection is
established, they will be discarded. ETPro will dial-up the ISP to establish an Internet
connection before attempting to open the server socket.
The remote server’s IP and port are part of the SerialNET mode configuration parameters.
Once a data connection is established data can flow freely between the local client device
and the remote server. If a connection cannot be obtained, eventually the client device’s
data will be discarded (similar to the case of a device transmitting serial data without a
serial cable connected).
Data continues to flow until a predefined activity termination event is triggered, upon
which the remote connection is dropped.
23.5.Automatic SerialNET Server Wakeup Procedure
A SerialNET client may be configured to wake up a remote SerialNET server provided it
has its phone number. The SPN parameter is used to store this wakeup number.
When SPN contains a phone number and no Host Server Name and/or IP are defined, the
SerialNET client will try to retrieve them from the registration Email of a remote
SerialNET server.
When characters are received from the host port, the SerialNET client will dial the
SerialNET server and then hang up, causing the server to connect to it’s ISP, send a
registration Email containing it’s IP address and local port, and open a listen socket on
that port.
The client, after waking up the server, connects to its ISP and starts polling the predefined
mailbox for the server’s registration Email. Once this Email arrives, the client opens a
socket to the IP address and port defined in the Email. The SWT (SerialNET Wakeup
Timeout) parameter will define how long ETPro will wait for this procedure to conclude
before stopping.
Data will then flow until a predefined activity termination event is triggered, upon which
the remote connection is dropped.

23.6.Transmit
Packets
.
Data originating in the local device is buffered, packetized and transmitted to the remote
system over the network. Packets are formed as a result of meeting at least one of the
following criteria:
1. A predetermined amount of bytes have been received from the local link (MCBF).
2. The TCP/IP connection MTU was met.
3. A predetermined flush character has been received (FCHR).
4. A predetermined inactivity timeout event was triggered (MTTF).
Until one of these events occurs, data is buffered in the ETPro. When an event occurs, a
packet is transmitted. The event parameters are configured by setting AT+i parameters
prior to initiating SerialNET mode. When a UDP connection is used, data packets are
atomic, maintaining their original size. When a TCP connection is used packets may be
combined before being actually transmitted. This follows from the stream nature of the
TCP protocol.
Data originating in the remote system is routed to the local device as it is made available.
Flow control may be governed locally using hardware flow control only.
23.7.Completing a SerialNET Session
A SerialNET session is complete when one of the following occurs:
1. The local device transmitted the disconnection string, as defined in the DSTR
parameter.
2. Following an inactivity timeout, as defined in the IATO parameter.
The ETPro will go offline when the SerialNET session is terminated.
23.8.SerialNET Failed Connection
If the ETPro fails to establish a SerialNET connection, SerialNET mode will be
deactivated for a delay period defined in the SNRD parameter.
23.9.
Local Serial Port Configuration
Prior to entering SerialNET mode, the ETPro’s local serial port may be configured to
comply with a wide range of devices by assigning a value to the SNSI parameter.

The ETPro shall be forced into SerialNET mode by issuing the following command:
AT+i[!]SNMD
If the minimal SerialNET parameters are defined, the ETPro will reply with ‘I/OK’,
followed by I/DONE or I/ONLINE.
If the ETPro was on-line when this command was issued, it will orderly close the Internet
session. This includes closing all open sockets and disconnecting from the ISP in a modem
environment.
When the ETPro boots up in SerialNET mode it will set the host serial channel to the fixed
baud rate and serial interface parameters defined in the SNSI parameter.
The ETPro is polled for the ‘RING’ string. If the ringresponse destination Email parameter
(RRMA) or ring-response server parameter (RRSV) contain values, the ETPro will wait for
the ‘RING’ strings to subside and connect to the Internet. Once on-line it will send an
Email to the RRMA address (if defined) and/or establish a socket to the address in RRSV
(if defined). The transmission will contain the dynamic IP address received from the ISP
and its Listen port, on which ETPro has an open listen socket, ready to serve the remote
client.
ETPro will go offline if one of the following events occur:
1.
The remote peer closed the SerialNET socket
2.
The IATO parameter was defined and timed-out
3.
The terminating string defined in the DSTR parameter was received
When the optional ‘!’ (“Auto-Link” mode) flag is specified, ETPro will immediately go
online in response to the AT+i! SNMD command. In this case, if one of the terminating
events occurs, ETPro will not go offline. Rather, the SerialNET socket will be closed
while ETPro will stay online.
ETPro will exit SerialNET mode when one of the Escape procedures is activated (see
preceding paragraph). The BDRF parameter will then govern the ETPro’s baud rate mode.

. Transfer Protocol (FTP) Theory of
24. File
Operation
24.1.Introduction
The FTP client component in ETPro Series extends the ETPro’s general-purpose sockets to
incorporate an additional, dedicated socket, for FTP activities. From the host’s perspective the
FTP capabilities are a logical extension of the capabilities of Email and direct socket
manipulation.
As in all other ETPro protocol implementations, host involvement in the specifics of FTP is kept
minimal. ETPro needs to deal with non-standard FTP issues, such as possible differences between
FTP server responses, on its own. Multi stage FTP protocol sequences are atomized under ETPro
control to minimize complexity and need for host processor intervention.
The FTP protocol is described in RFC 959.

25. Telnet
Client Operation
.
There are four operation modes for most Telnet applications, namely, half-duplex,
character at a time, line at a time, and line-mode.
ETPro incorporates two methods to send data to the remote Telnet server: “One line at a
time”, namely an AT+i command (+iTSND) is used to send a single (CR/LF terminated
line to the Telnet server); and “Binary Transmission”, where an AT+i command
(+iTBSN) is used to send an arbitrary amount of binary data.
Data is retrieved from the remote Telnet server as it is made available. Embedded Telnet
options in the server’s response stream are stripped by ETPro before being turned over to the
host.
Telnet specifies many operational options. The ETPro will restrict its operation mode to
the minimum implementation to assure best intersystem compatibility. The following
are the only Telnet options that will be negotiated by ETPro:
Any other options negotiated by the Telnet server will be rejected by ETPro.

26. Remote AT+i Service
26.1.Introduction
The LATI parameter allows configuring ETPro to maintain a communication channel, which
supports interacting with ETPro from a remote location, using the AT+i command set, as-if the
commands are administered through the local serial port. When LATI is set to a non-zero value,
ETPro will open a TCP listen socket on port <LATI>. This will only occur after the PPP
connection is established. This listen socket may be used to connect to the ETPro’s remote
AT+i service.
26.2.Remote AT+i commands
When a remote client connects to ETPro’s LATI socket, ETPro redirects the socket’s data flow
to the AT+i parser, in effect allowing the socket to take over the parser. Any data coming from
the socket will be processed by the ETPro, as if it came from the host serial port and the replies
will be returned to the socket instead of being send to the host serial port. ETPro will reply with
an “I/BUSY” to commands coming from the host serial port, while the remote client is
connected.
An exception to this is the "+++" Escape sequence. On detection of "+++" from the host serial
port, ETPro will close the remote connection and reboot.
If ETPro was in the process of performing some Internet activity, initiated by the host, at the
time the remote client connected, ETPro will allow this activity to end and the final reply to
reach the host before passing control over the parser to the remote client.
26.3.Closing a Remote AT+i Session
To close a remote AT+i session, the remote client can choose to issue AT+IDOWN via the
socket. In response to this, ETPro will restart (only I/OK will be returned over the socket before
it is closed by ETPro). Alternatively, the remote client may close the socket in order to
disconnect, leaving the ETPro’s Internet session as is. In the later case, ETPro will return
control over the parser to the local host port. The LATI listen will remain active, available to
service additional remote connections.
ETEK R&D CO.,LTD
145
..
.
After a LATI..session is closed, the LSR (last session error) WEB parameter will contain the
value 096 to ..indicate that a LATI session has been disconnected.
..
Note: ‘+++’ sent over the LATI socket will not be recognized as an Escape Sequence.
26.4.Caveats and Restrictions
a. When ETPro Series is in auto baud rate detection mode (after restarting with
BDRF=’a’ or in response to the AT+iBDRA command), a remote AT+i session
cannot be established, even if the LATI parameter contains a port value.
b. During a remote AT+i session, the remote client taking over the parser cannot
make use of ETPro’s mechanisms of Hardware or Software flow control, which
exist for the local host port. The only mechanism ETPro will use is this mode is
TCP level flow control (using the TCP window).

27.3.75 +iIATO - Inactivity Timeout
Syntax: AT+iIATO=n
Permanently set maximum inactivity timeout
in seconds to signal socket disconnection in
SerialNET mode. When signaled, ETPro will
close the connected SerialNET
communication socket. In a modem
environment the ETPro will also go offline,
following this event.
Parameters:
n = number of seconds of inactivity, on a
connected SerialNET socket, to signal socket
disconnection.
Command Options:
n = 0 .. 32768
When ETPro is in Server SerialNET mode (LPRT
defined) and it goes online, in response to a triggering
event: RING signal, MMSEL/LMSEL signal pulled
low or AT+I! SNMD -- timeout calculation
commences only after the ETPro opens the Listen
port. When the Web server is activated (using
AWS=1), an external reference to the Web server will
restart the IATO timeout calculation.
Default:
0 – No timeout limit
Scope:
ETPro Series
Result code:
I/OK
I/ERROR
Otherwise
