there's nothing secret about that AT command profile.  The chipset
supports all of the mandatory ETSI GSM TS 07.07 commands (use 
http://pda.etsi.org/pda/queryform.asp to get it), plus some of the
optional ones.

This GSM standard even has a command that lists the list of available
commands (AT+CLAC). See attachment.

There are some vendor-specific, proprietary TI AT commands which will
remain undocumented. But none of them are required for regular phone
usage (including SMS, MMS, FAX, GPRS, Voice Call, Data Call (CSD), etc.)

So I really don't understand all this fuzz.  It's really very much
standard compliant.

As for the fax, it's just regular ITU-T.32 class 2.0
