GSM modem AT command spec and application developer's guide shouldn't be 
NDA stuff, since GSM modems are available also as separate boxes which 
can be controlled by the buyer with PC.  So any part of the interface 
cannot be kept "secret". So I'm quite sure that if the TI contact person 
in FIC just asked for the spec, it should be no problem to publish them 
to developers.
I tried to search more information about Calypso in TI's web pages but 
couldn't find anything.
