GPRS AT comands for Release 99

Hi all,

I am writing a specificaion about GPRS AT commands for release 1999. As I am new for this topic , I am not sure how it run and the concept for this topic. Do youth guys currently get some documentations or user guide that can give me some reference? Many thanks .


(P.S. the command I need to write for are +CGTFT, +CGANS, +CGDATA... I already got the GSM specification for them, the problem I met now is that I do not know how to give examples for them)
