1.3 Definitions
For the purposes of the AT-commands interface description in this
document, the following definitions apply:
Command mode:
In Command mode, the modem is not
communicating with a remote station, and is ready
to accept commands. When powering-up, the
modem automatically enters this mode, and
automatically returns to this mode when a call is
disconnected.
Online mode:
Also called data mode: In Online mode, the modem
is communicating with a remote station. Data
coming through the RS232 serial link are treated as
data and transmitted to the called part, and data
received from the called part are transmitted to the
terminal through the RS232 serial link. Online mode
is activated by successful completion of a command,
either manually or automatically, to originate or
answer a call, or by receiving the ATO command to
return to online mode from Command mode.
[...]:
Items enclosed in square brackets are optional.
The square brackets themselves must not appear in
the command line.
<...>:
Some syntactical elements are mentioned enclosed
in angle brackets. Actually the meaning (values) for
those elements must appear in the command and
the angle brackets are omitted.
All other characters, including " " ", "&", "?", "=
=", parentheses, etc., shall
appear in commands as written.

3 AT Commands interface
This chapter describes the interface based on the Hayes protocol
standard between the TE and the ME. The AT commands presented
here in are intended to manage voice, data and fax communication
as well as SMS sending and receiving.
3.1 Command syntax
There are 3 types of commands:
1. Set command:
using the = (equal) character, it is possible to assign a value
to a parameter.
2. Read command:
using the ? (question mark) character, it is possible to read the
current setting of a parameter.
3. Test command:
using the character sequence =? (equal followed by question
mark), it is possible to test if a parameter is supported by the
modem and to read the supported values for that parameter.
Examples:
AT+CPIN=####
' to enter the PIN code of the SIM.
ATS0?
' to determine the number of ring indicators
awaited before automatically answering.
AT+COPS=?
' to determine which PLMN are currently
available.
The following only applies in command mode.
All available commands for the WMO2 modem line are presented in
the chapter 4.

3.1.1
Friday 21 May 1999
Request syntax
3.1.1.1 Basic syntax
At fixed baud rate uppercase or lowercase letters can be used to
type in the AT-Commands. But the use of both upper and lowercase characters in the same command is not permitted.
The end character, except in some cases for which it is indicated, is
always the <CR> (Carriage Return) character.
The syntax is based on the nominal Hayes standard:
•
Each command begins with a 2 letters prefix "AT" (ATtention)
except the "+++" and the "A/" commands;
•
The command's body is a single character or an
& (ampersand) character immediately followed by a single
character;
•
A + (plus) character may immediately follow the AT prefix to
indicate it is an extended command format in that case, a
letter (chosen among the following one: A, C, D, E, F, G, I, M,
S, T, V or W) immediately follows the + character, then comes
the command itself (the body);
•
The parameters (if any) of the command are placed at the end.
Examples:
ATA
AT&W
ATQ1
ATS0=2
'
'
'
'
to

to
answer a call.
store the profile in memory.
suppress the extended syntax result codes.
automatically answer a call after 2 rings.
It is possible to concatenate several commands on the same
command line, example: ATQ1S0=2;&W
You must insert a ; (semicolon) straight after each command that
use a = (equal) or ? (question mark) character and after each
extended format command.
There is no need of any special character for all other commands
(i.e. there are no ; (semicolon) between the Q1 and S0=2
commands above, but there is one straight after the S0=2
command before the &W command.
3.1.1.2 Special cases
If the serial link exchange baud rate is not fixed, case of the modem
working in autobauding mode, it is not possible to type in the
commands using lowercase characters.
When sending SMS messages, the end character is no longer the
<CR> (carriage return), it is the <CTRL>Z character (Escape
character).

3.1.2
Friday 21 May 1999
Answer syntax
There are 2 types of answers: information text and result codes.
The answer of a command may be build of both an information text
and a result code.
The answer may be transmitted in numeric form or alphabetic
(verbose) form depending upon the setting of the V parameter.
The response, either in numeric form or in alphabetic form, consists
of a header, a body and a trailer.
The header and the trailer are the same, there are build with 2
characters <CR> <LF> (Carriage return and Line Feed).
This applies for all commands except the V0 and the Q1
commands.
When the command syntax is wrong, the modem responds ERROR.
When the command syntax is correct but with incomplete or
incorrect parameters, the modem responds +CME ERROR: <Err> or
+CMS ERROR: <CMSErr> with the corresponding error code (<Err>
respectively <CMSErr>).
If the command syntax is correct and all parameters are valid but
the network refuses the command whatever the reason, the modem
responds +CMS ERROR: <CMSErr>, where <CMSErr> is the
reason (if any) given by the network.
The modem responds OK when the network accepted the
command and both the syntax and the parameters where correct.
For some commands such as "AT+CPIN?" or "AT+EXPKEY?" or
"ATQ1", the modem will not give the OK string at the end of the
command execution.
Moreover there are 3 sub-types of answers. These sub-types
describe answers that are return at different states of the modem.
Final result type
: indicates the full completion of an AT
command and can be considered as a
willingness to accept new commands
from the TE. Example: "OK" or "ERROR".
Intermediate result type
: is a report of the execution progress of
the currently being treated AT
command. Example
"CONNECT <speed>".
Unsolicited result type
: indicates the happening of an event
not directly ensuing from a previous AT
command. Example "RING".

3.3 Global behaviour
3.3.1
SIM Insertion, SIM Removal
SIM card Insertion and Removal procedures are supported. These
are software functions based on the reading of the hardware SIM
presence pin. This pin state (open/closed) is continuously watched.
When the SIM presence pin indicates a presence of "somewhat" in
the SIM connector, the module tries to establish a SIM logical
session. Depending if the "somewhat" is a SIM Card or not, the SIM
logical session will be successfully established or not.
The AT+CPIN? command delivers the following answers:
•
If the SIM presence pin indicates "nothing", the answer to
AT+CPIN? is "+CME ERROR: 10" (SIM not inserted).
•
If the SIM presence pin indicates "something" and the
inserted Card is a valid SIM Card, the answer to AT+CPIN?
is "+CPIN: xxx" depending of the SIM PIN state.
•
If the SIM presence pin indicates "something" and the
inserted Card is not a valid SIM Card, the answer to
AT+CPIN? is "CME ERROR: 10".
•
These both last status are not immediately available after
powering-up due to the background initialisation. During
this step and before the SIM presence pin indicates
"somewhat", the AT+CPIN? command returns
"+CME ERROR: 515" (Please wait, initialisation in progress).
When the SIM presence pin indicates "nothing" and the previously
inserted SIM Card was removed, an IMSI detach procedure is
executed, and all the user data corresponding to this previous SIM
are removed from the memory (Phonebooks, SMS etc.).
The modem can then still emit calls but only in the emergency
mode (only emergency numbers can be dialled).

WCOM/GSM/WMO2/WMO2ATDOC
3.3.2
Friday 21 May 1999
Background initialisation
After a valid PIN entry, many SIM user data information are loaded
in the modem memory (Phonebooks, SMS status…). This operation
can last a long time when reading huge phonebooks.
The AT+CPIN? command answers just after verification of the PIN.
User Data are loaded in background after the PIN checking.
This means, that some data of the SIM may not be available
straight after the "OK" (if PIN is valid) of the PIN Entry function was
received by the TE. Data that may be affected are particularly the
phonebook's entries.
So that any access to phonebooks features will then be refused by
the following error message "+CME ERROR: 515" or
"+CMS ERROR: 515" meaning "please wait, service is not available,
initialisation in progress".
Also this kind of answer may be returned by the modem in several
circumstances:
•
when trying to execute another AT command before the
previous one was executed to the end.
•
when swapping from (or to) ADN to (or from) FDN and
trying to immediately read the concerned phonebook;
•
when giving the +CPIN? command (SIM Status) just after a
SIM insertion and before the modem could execute a valid
SIM Card logical session.

4.1.11 Set phone functionality +CFUN
This command selects the level of functionality in the mobile station.
Command syntax:
AT+CFUN=<L>
Parameters:
<L>
id to be set as described below.
When the application wants to stop the module to make a power off, or if
the application wants to force the module to execute an IMSI DETACH
procedure, then it has to send:
AT+CFUN=0
(same as AT+CPOF)
This command executes an IMSI DETACH and makes a backup of some
internal parameters in the SIM and the EEPROM. Then no more access to the
SIM card is possible.
If the mobile is not powered off after this command, it shall received
another command to re-start the whole GSM process.
If the mobile is turned off after this command, then the power on will
automatically execute the start of the whole GSM process.
When the application wants to re-start the module (after having done a
AT+CFUN=0 command, and without having cut the power supply), it has to
send:
AT+CFUN=1
This command starts again all the GSM stack and GSM functionality, a
complete software reset is done. All parameters are reset to their previous E2P
value if AT&W was not used.
If you write entries in phonebook (+CPBW) and then reset the module
directly (AT+CFUN=1, without any AT+CFUN=0 before), some entries may not
be written (SIM task did not have enough time to write the entries in SIM card)
Also, the OK response will be sent at the last defined baud rate defined by
+IPR command. With autobauding the response can be at a different baud rate,
so it is better to save the defined baud rate with AT&W before directly send the
AT+CFUN=1 command.
Example:
Application to GSM AT+CFUN?
GSM to application +CFUN: 1

Application to GSM AT+CFUN=0
GSM to application OK
Application to GSM AT+CFUN=1

Example:
For a data or fax call, the application sends to the GSM module the
following ASCII string: (the bearer has to be selected before with the
+CBST command)
ATD1234
Calling number 1234 (data or fax).
For a voice call, the application sends to the GSM module the following
ASCII string: (the bearer may be selected before, if not a default bearer is
used)
ATD5678;
Calling number 5678 (voice call).
Please, notice that in case of an international number, the local
international prefix has not to be set (usually 00) but need to be replaced by
the '+' character. That is to establish a voice call to the Wavecom company
from another country, the AT command shall* be:
ATD+33146290800; Calling Wavecom from Germany (for example).
Dialling from a phonebook location (stored in SIM card) can be done with
the following command:
ATD> 5;
To call (voice call) the 5th entry from the
selected phonebook (through +CPBS
command) .
ATD> "BILL";
To call "BILL" (voice call) from the selected
phonebook.
ATD> FD 1

<mode>:
0: Deactivate Echo
1: Activate Echo
2: Configure the echo cancelation (automatically stored in E2P)
<Taps>: Number of taps of the adaptive filter. This value is directly
related to the length of the longest echo path (240 words = 30 ms echo
path delay). Values from 1 to 192, default is 160
<ConvTh>: Threshold for convergence parameter. This specifies the level of
energy computed on <EcDelay> samples needed to assume algorithm
convergence. A low value provides a high convergence and a high value a
high stability. Values from 0 to 45, default is 12.
<DbtS>: Double talk sensitivity. This reflect the ratio between received
and sent energy to assume double talk occured. A low value provides a
high sensibility and a high value a low one. Values from 0 to 10, default is
5.
<FarS>:
Far end speaker detection - algorithm adaptation. This is related
to then energy level needed on the receive path to allow filter taps
adaptation. If <FarS> = 0 the algorithm will always adjust the filter. Values
from 0 to 1000, default is 512.
<EcDelay>: Number of samples used to compute energy for algorithm
convergence evaluation. Values from 1 to 30, default is 10

To select the operator, three possibilities exist:
1- The mobile enters the manual mode, and then try to find an operator
which is indicated by the application. If it finds and registers correctly, then
the mobile stays in idle mode.
2- The mobile enters the automatic mode, and then try to find the home
operator. If it finds and registers correctly, then the mobile stays in idle
mode ; if not, the mobile search automatically another network.
3- The mobile enters the manual/automatic mode, and the try to find an
operator which is indicated by the application (like in manual mode) . If this
attempt fails the automatic mode is entered.
To force an attempt to select and register a network operator, the
application must send the following command:

4.4 Security commands
4.4.1
Enter PIN
+CPIN
This command is used to enter ME passwords (CHV1 / CHV2 / PUK1 /
PUK2…) which are needed before any other functionality of the ME can be
used. The CHV1/CHV2 length is between 4 and 8 digits, the PUK1/PUK2
length is 8 digits only.
If the user application try to establish an outgoing call before having
validated the SIM PIN code (CHV1), then the GSM module will refuse the
"ATD" command with a "+CME ERROR: 11" (SIM PIN required).
It's up to the application to validate the PIN after each reset or power on if
the PIN was enabled. The application shall therefore use the command:
AT+CPIN=<pin>
Application to GSM
GSM to application
Application to GSM
GSM to application
AT+CPIN=1234
OK
AT+CPIN=5678
+CME ERROR: 3
Enter PIN
PIN code is correct
Enter PIN
Operation not allowed, PIN previously entered
After 3 unsuccessful codes, the PUK will then be required. The PUK
validation forces the user to enter as a second parameter a new PIN code
which will be the new PIN code if the PUK validation succeeds. The CHV1
is then enabled if the PUK1 is correct. The application shall therefore use
the command:
AT+CPIN=<Puk>,<NewPin>
Application to GSM
GSM to application
Application to GSM
GSM to application
AT+CPIN=00000000,1234
+CME ERROR: 16
AT+CPIN=12345678,1234
OK
enter PUK and new PIN
Incorrect PUK
enter PUK and new PIN, 2nd attempt
PUK correct, new PIN stored
To know which code has to be entered (or not), the following interrogation
command can be used:
AT+CPIN?
The possible responses are:
+CPIN: READY
ME is not pending for any password
+CPIN: SIM PIN
CHV1 is required
+CPIN: SIM PUK
PUK1 is required
+CPIN: SIM PIN2
CHV2 is required
+CPIN: SIM PUK2
PUK2 is required
+CPIN: PH-SIM PIN
SIM lock (phone-to-SIM) is required
+CPIN: PH-NET PIN
Network personnalisation is required
+CME ERROR: <err> SIM failure (13) absent (10) etc...
Please note that in this case the mobile does not finish its response with
the OK string.
The response +CME ERROR: 13 (SIM failure) is returned after 10
unsuccessful PUK presentations. The SIM card is then out of order and
shall be replaced by a new one.

If the user try to do something which requires PIN2 (CHV2) the GSM
module will refuse his action with a “+CME ERROR: 17” (SIM PIN2
required). Then the GSM module is waiting SIM PIN2 to be given.
Of course if SIM PIN2 is blocked , SIM PUK2 is required instead of SIM
PIN2.
For instance, the GSM module needs PIN2 to write in the fixed dialling
phonebook (FDN) , so if SIM PIN2 authentication has not been done during
the current cession the SIM PIN2 is required:
AT+CPBS=”FD”
Choose FDN
OK
AT+CPBW=5,"01290917",129,"Jacky"
write in FDN at location 5
+CME ERROR:17
SIM PIN2 is required
AT+CPIN?
SIM PIN2
SIM PIN2 is required
AT+CPIN=5678
Enter SIM PIN2
OK
AT+CPBW=5,"01290917",129,"Jacky"
write in FDN at location 5
OK
Now writing in FDN is allowed
Please note that the GSM module ask only once PIN2 or PUK2, so if they
aren’t entered right, the next +CPIN? command will return “+CPIN:
READY”.
Remark
In the way Application to GSM, an "h" character shall be added before the
PIN value if cyphering mode (with D.E.S algorithm ) is on. See +EXPKEY
command.
Same remark for +CLCK and +CPWD commands.

Enter PIN2 +CPIN2
This specific command is used to validate the PIN2 code (CHV2), or to
validate the PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code.
Of course +CPIN command allows to validate PIN2 or PUK2 codes but only
when the last executed command resulted in PIN2 authentification
failure.

Preferred Message Format
+CMGF
The formats implemented are the text mode and the PDU mode.
In PDU mode, a complete SMS Message including all header information is
passed as a binary string (in hexadecimal format, so only this set of
characters is allowed: {‘0’,’1’,’2’,’3’,’4’,’5’,’6’,’7’,’8’,’9’, ‘A’,
‘B’,’C’,’D’,’E’,’F’} ). Each pair or characters is converted to a byte (ex: ‘41’ is
converted to the ASCII character ‘A’, whoes ASCII code is 0x41 or 65).
In Text mode, every commands and responses are in ASCII characters.
The chosen format is stored in E2PROM by the command +CSAS.

The message <pdu> is composed of the SC address (« 00 means no SC
address given, use default SC address read with +CSCA command) and the
TPDU message.
The length of octets of the TPDU buffer is 14, coded as GSM 03.40
In this case the TPDU is: 0x01 0x03 0x06 0x91 0x21 0x43 0x65 0x00
0x00 0x04 0xC9 0xE9 0x34 0x0B, which means regarding GSM 03.40:
<fo>:
0x01 (SMS-SUBMIT, no validity period)
<mr> (TP-MR):
0x03 (Message Reference)
<da> (TP-DA):
0x06 0x91 0x21 0x43

TPDU in hexadecimal format must be converted into two ASCII characters,
e.g. octet with hexadecimal value 0x2A is presented to the mobile as two
characters ‘2’ (ASCII 50) and ‘A’ (ASCII 65).

The <address> field is the address of the terminal network to whom the
message is sent. To send the message, simply type <ctrl-Z> character
(ASCII 26). The text can contain all existing character except <ctrl-Z> and
<ESC> (ASCII 27).
This command is abortable using the <ESC> character when entering text.
In PDU mode, only hexadecimal characters are used (‘0’...’9’,’A’...’F’).

The message reference <mr> which is returned back to the application is
allocated by the GSM module. This number begins with 0 and is
incremented by one for each outgoing message (successful and failure
case) ; it is cyclic on one byte (0 follows 255).
Note: this number is not a storage number - outgoing messages are not
stored.

RP UDHI SRR VPF RD MTI
RP: Reply Path, not used in text mode.
UDHI: User Data Header Information, b6=1 if the beginning of the User
Data field contains a Header in addition to the short message. This option is
not supported in +CSMP command, but can be used in PDU mode
(+CMGS).
SRR: Status Report Request, b5=1 if a status report is requested. This
mode is supported.
VPF: Validity Period Format
b4=0 & b3=0 -> <vp> field is not present
b4=1 & b3=0 -> <vp> field is present in relative format
Others formats (absolute & enhanced) are not supported.
RD: Reject Duplicates, b2=1 to instruct the SC to reject an SMS-SUBMIT
for an SM still held in the SC which has the same <mr> and the same
<da> as the previously submitted SM from the same <oa>.
MTI: Message Type Indicator
b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS)
b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC)
In text mode <vp> is only coded in "relative" format. The default value is
167 (24 hours). This means that one octet can describe different values:
VP value
Validity period value
0 to 143
(VP + 1) x 5 minutes

197 to 255 (VP - 192) x 1 week
<pid> is used to indicate the higher layer protocol being used or indicates
interworking with a certain type of telematic device. For example, 0x22 is
for group 3 telefax, 0x24 is for voice telephone, 0x25 is for ERMES.

4.6.16 Service center address
Friday 21 May 1999
+CSCA
This command shall be used to indicate to which service center the
message has to be sent.
The GSM module has no default value for this address. If the application
tries to send a message without having indicated the service center
address, an error will be generated.
So, the application has to indicate this address at initialization. This address
is then valid all the time. The application may change it if needed.

Note (1): first set of values indicates the range of autodetectable speeds.
The second set of values indicates all the possible speeds which can be
used by DCE.
An autobauding is provided which operates from 2400 to 19200 baud.
However some constraints have to be dealt with:
• any AT command issued by DTE must start with a capital ‘A’ and
‘T’ (or ‘\’). If not, DCE may send back some garbagge characters
and get de-synchronized. Shoud it happen, DTE shall just issue
once or twice ‘AT\r’ (at 2400 or 4800 baud) or just ‘AT’ (at 9600
baud) to get the modem re-synchronized.
• the DTE shall wait for 1ms after receipt of the last character of the
AT response (which is always ‘\n’ or 0x0A) to send a new AT
command at either the same rate or a new rate. Shoud this delay
ignored, DCE can get de-synchronised. Once again, sending once
or twice ‘AT\r’ or just ‘AT’ causes the DCE to recover.
Be careful: at start-up if autobauding is enabled and no AT command has
been received yet, the module sends all unsolicited responses (like RING) at
9600 baud.

through RTS) the behavior of the DCE is the following:
If the DCE has never detected RTS in high (or ON) condition since startup
then it ignores RTS, assuming this signal is not connected.
As soon as DCE detects RTS high, then this signal acts upon it. Therefore
subsequent RTS transition to OFF will prevent DCE from sending any
further data in online and in offline as well.
This behavior allows the user to use the default settings (hardware flow
control) and let RTS disconnected. In the case RTS is connected and is high
at least once then it acts upon DCE.

Specific AT commands
4.10.1 Cell environment description +CCED
This command can be used by the application to retrieve the cell
parameters of the main cell and of up to six neighbour cells.
Two ways may exist for the external application to know these cell
parameters: on request of the application, or automatically by the module
every 5 seconds.
The automatic mode is not supported during communication or
registration.
The command to manage this functionality is:
Command syntax:
AT+CCED=<mode>[, <requested dump>]
* <mode>:
0
1
2
One shot requested
Automatic shots requested
Stop automatic shots
* <requested dump>:
1
2
4
Main Cell:
MCC, MNC, LAC, CI, BSIC,
BCCH Freq (absolute), RxLev,
RxLev Full, RxLev Sub,
RxQual, RxQual Full, RxQual
Sub,Idle TS
Neighbour1 to Neighbour6:
MCC, MNC, LAC, CI, BSIC,
BCCH Freq (absolute), RxLev
Timing Advance
Combination (addition of the values) of the requested dumped are
supported.
Notice that in idle mode, only RxLev measures (one the main cell and on
the neighbour cells) are done. The value of these RxLev is set in the RxLev
Full field for the main cell.
The response will be:
+CCED:<value>, ... , <value>
OK
Where <value> is the ASCII string of the values (in hexadecimal) of the
parameters. If a field can not be measured - or has no sense - the
parameter is not filled (two consecutive commas are then found).

4.10.2 Automatic RxLev indication
+CCED
The CCED command has been extended to indicate the the received signal
strength indication (rssi) of the main cell. The principle of the command is
not changed:
Command Syntax:
AT+CCED=<mode>[, <requested dump>]
* <mode>:
0
1
2
One shot requested
Automatic shots requested
Stop automatic shots
* <requested dump>:
8 Main cell RSSI indications (RxLev) from 0 to 31
The response will be a +CSQ answer and not a +CCED answer. The 07.07
format for the +CSQ is respected. The <ber> is not evaluated by this
command, so the <ber> value will always be 99.
+CSQ:<rssi>, 99
OK
This +CSQ answer, when automatic shots are selected, is sent every time
the <rssi> measured by the module changes. This automatic shots are
supported in idle mode and during communication.
Combination (addition of the values) of the requested dumped (1,2,4,8) are
supported. Both answer +CCED and +CSQ may be then generated.

4.10.3 General Indications +WIND
Wavecom introduced a general mechanism to send unsollicited non
standardized indication to the customer application. The yet identified
unsollicited non standardized indications are:
- indication of a physical change on the SIM presence pin from
connector (meaning SIM inserted, SIM removed)
- indication during a mobile originated call establishement, that the
calling party is ringing.
- Indication of the availability of the module, after boot, to receive AT
commands
For each of these indications, a “bit flow” has to be indicated. The syntax of
the command is:
Command syntax:
AT+WIND= <IndLevel >
<IndLevel>
1
2
4
8
Indication
Hardware SIM Insert / Remove indications (Rack open/close)
Calling party alert indication
Module is ready to treat AT commands (except phonebooks, AOC, SMS), but still in
emergency mode.
Indication that the module is ready to treat all AT commands, at te end of init, or
after ADN / FDN swap
If <IndLevel> is equal to 0 (default value), no unsolicited
“+WIND: <IndNb>” will occur.
Combination (addition of the values) shall be used to allow more than one
indication flow.
The answer is OK if the value are in the previous range.
The unsolicited answer will then be:
+WIND: <indicated event>
The yet defined indicated event list is:
<event>
0
1
2
3
4
Meaning
The SIM presence pin has been detected as “SIM removed” (depending from the 0 bit
flow)
The SIM presence pin has been detected as “SIM inserted”
Calling party is alerting
Module is ready to treat AT commands (except phonebooks, AOC, SMS), at init or after
AT+CFUN=1
Module is ready to treat all AT commands, end of phonebook init or swap (ADN to
FDN, or FDN to ADN)
AT+WIND? Command is supported and indicates the <allowed bit flows>.
AT+WIND is automatically stored in e2p. This means the &W commands
has not to be used. And the selected flows are always activated after boot.
Default value is 0: No flow activated. No indication.

Fax Management commands
The fax service provided by the module is class 1 compatible. However only
the core commands defined by ITU T.31 are supported. These are:
•
AT+FRH=3, AT+FRH=?,
•
AT+FTH=3, AT+FTH=?,
•
AT+FRM=24,48,72,96, AT+FRM= ?,
•
AT+FTM=24,48,72,96, AT+FTM= ?,
•
AT+FRS= <any duration>,
•
AT+FTS= <any duration>.
It means that commands like AT+FAR, +FCC,... are not supported.
4.12.1 Setting up the module for fax
When autobauding is enabled, nothing special has to be done. However
when not enabled, proceed as described below to set up the module for
fax.
The GSM unit as well as the PC fax application have to be properly set up
prior to sendind/receiving faxes.
The only thing to do is to change the serial link rate as follows:
a) Launch any terminal application on PC and set it up to 9600 baud.
b) From the terminal application type in: AT+IPR = 2400; &W <enter>
The GSM unit should reply OK (if not, type in 'AT<enter>' as long as it does
not answer 'OK' and start again stage b).
4.12.2 Setting up the PC fax application:
The recommended fax application is Delrina WinFax v8.0.
It should be configured as follows (menu Setup/Fax Modem Setup):
♦ Port: any com
♦ Model: Generic Class 1 (hardware flow control). A generic class 1
with software flow control can be also selected.
♦ Init: default string is suitable for the module
♦ Reset: default string is suitable for the module
♦ Maximum Transmit Rate: 9600 baud (if higher then rate will be
automatically cut back to 9600 baud).
Others settings are of no relevance for the GSM unit: they can be modified.
4.12.3 Restoring the module's default profile for data call.
As for setting up the module for fax, the following instructions are
irrelevant if autobauding is enabled.
If the module is configured as stated in 10.1 then the serial rate is 2400
baud which of course limits the overall thoughput in support of 4800/9600
data calls.
Therefore, the serial rate should be set back to 9600 (or better 19200) baud
by issueing: AT+IPR = 9600; &W <enter>

Cause no 1: "Unassigned (unallocated) number"
This cause indicates that the destination requested by the Mobile Station
cannot be reached because, although the number is in a valid format, it is
not currently assigned (allocated).
Cause no 8: "Operator determined barring"
This cause indicates that the MS has tried to send a mobile originating
short message when the MS's network operator or service provider has
forbidden such transactions.
Cause no 10: "Call barred"
This cause indicates that the outgoing call barred service applies to the
short message service for the called destination.
Cause no 21: "Short message transfer rejected"
This cause indicates that the equipment sending this cause does not wish
to accept this short message, although it could have accepted the short
message since the equipment sending this cause is neither busy nor
incompatible.
Cause no 27: "Destination out of service"
This cause indicates that the destination indicated by the Mobile Station
cannot be reached because the interface to the destination is not
functioning correctly. The term "not functioning correctly" indicates that a
signalling message was unable to be delivered to the remote user; e.g., a
physical layer or data link layer failure at the remote user, user equipment
off-line, etc.
Cause no 28: "Unidentified subscriber"
This cause indicates that the subscriber is not registered in the PLMN (i.e.
IMSI not known)
Cause no 29: "Facility rejected"
This cause indicates that the facility requested by the Mobile Station is not
supported by the PLMN.
Cause no 30: "Unknown subscriber"
This cause indicates that the subscriber is not registered in the HLR (i.e.
IMSI or directory number is not allocated to a subscriber).
Cause no 38: "Network out of order"
This cause indicates that the network is not functioning correctly and that
the condition is likely to last a relatively long period of time; e.g.,
immediately reattempting the short message transfer is not likely to be
successful.
Cause no 41: "Temporary failure"
This cause indicates that the network is not functioning correctly and that
the condition is not likely to last a long period of time; e.g., the Mobile
Station may wish to try another short message transfer attempt almost
immediately.
Cause no 42: "Congestion"
This cause indicates that the short message service cannot be serviced
because of high traffic.
Cause no 47: "Resources unavailable, unspecified"
This cause is used to report a resource unavailable event only when no
other cause applies.
Cause no 69: "Requested facility not implemented"
This cause indicates that the network is unable to provide the requested
short message service.
Cause no 81: "Invalid short message transfer reference value"
This cause indicates that the equipment sending this cause has received a
message with a short message reference which is not currently in use on
the MS-network interface.
Cause no 95: "Invalid message, unspecified"
This cause is used to report an invalid message event only when no other
cause in the invalid message class applies.

Cause no 96: "Invalid mandatory information"
This cause indicates that the equipment sending this cause has received a
message where a mandatory information element is missing and/or has a
content error (the two cases are undistinguishable).
Cause no 97: "Message type non-existent or not implemented"
This cause indicates that the equipment sending this cause has received a
message with a message type it does not recognize either because this is a
message not defined or defined but not implemented by the equipment
sending this cause.
Cause no 98: "Message not compatible with short message protocol state"
This cause indicates that the equipment sending this cause has received a
message such that the procedures do not indicate that this is a permissible
message to receive while in the short message transfer state.
Cause no 99: "Information element non-existent or not implemented"
This cause indicates that the equipment sending this cause has received a
message which includes information elements not recognized because the
information element identifier is not defined or it is defined but not
implemented by the equipment sending the cause.
However, the information element is not required to be present in the
message in order for the equipment sending the cause to process the
message.
Cause no 111: "Protocol error, unspecified"
This cause is used to report a protocol error event only when no other
cause applies.
Cause no 127: "Interworking, unspecified"
This cause indicates that there has been interworking with a network
which does not provide causes for actions it takes; thus, the precise cause
for a message which is being send cannot be ascertained.
All values other than specified should be treated as error Cause No 41
