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>
