Hi.

Where can I find the Nokia protocol? I can't understand what are the AT commands for? Where can I find a comprehensive info about the commands like:
AT
AT+CMGF=1
AT+CMGL
ATZ
AT+CMGS
etc.
I would like to understand the NavMicroSystems's program, but I can't without the protocol.
Please give me some usefull links, bacause I would also like to control my PIC with a SMS.

Thanks
