  • For information about the AT commands supported by your GSM modem and how to use them you will, obviously, have to read the Manual for your particular make and model of modem.

    See: www.8052.com/.../160143

    As far as the GSM modem is concerned, it is entirely irrelevant that the commands are being sent by a microcontroller.

    As far as the microcontroller is concerned, it is simply a matter of sending and recieving serial data - the fact that it's a GSM modem is entirely irrelevant.
