Catching responce of AT Commands...

Share your ideas which will be best way of getting data from GSM Module over UART using AT Commands..

I am using PIC16F877A,
There are two different ways i can think of,
1. Using UART Receive interrupt..
2. Using polling (busy in loop continuous receiving of data)..

I am programming PIC in C language "mikroC PRO for PIC"..
I have only code the functions for sending message command, and some other related function..

When i send any command eg "Send Message", "Check Signal Status" in return GSM module sends back a stream of data..
I am feeling difficulty in managing of the data.
Share your ideas to manage receiving data....


Thanks.
