1.11 Fax class 1 commands
The fax service provided by the module is class 1 compatible. However only
the core commands defined by ITU T.31 are supported. It means that
commands like AT+FAR, +FCC, etc are not supported. Autobauding has
to be enabled to set up the module for fax. All set commands below
(except AT+FCLASS) return an ERROR response code if they are not
issued during the communication.
1.11.1 AT+FCLASS
This command puts the module into a particular mode of operation (data or
fax).
Command Possible responses
AT+FCLASS= OK
AT+FCLASS? +FCLASS:
AT+FCLASS=? +FCLASS: (list of supported s)
