How to Send ATD and ATA commands from controller to GSM Modem through UART.

Can anybody Plz send me the source code in C language
 

does it work on hyperterminal


atd+91xxxxxxxxxxx; is for dial the number

for incoming call : When the product receives a call, it sets the RingInd signal and sends the ASCII “RING” or “+CRING: <type>” string to the application (+CRING if the cellular result code +CRC is enabled). Then it waits for the application to accept the call with the ATA command.
