Hi through mic we cannot give commands, interface ur modem serially and send commands 1 by 1 through serial port.
 

Hi,

You can give commands to gsm with serial port. If you want to give command through mic, you have to first execute UART of microcontroller and have to send the same commands using UART which you are sending with terminal software(e.g. hyperterminal).
