You'll need to show us the GSM modem make/model...which PIC type, compiler type and version you're using, as well as your attempt to make the code.
With literally thousands of 'GSM modems' available they are NOT all the same !
Links to design specs are good...'silly' little things like is the modem 5V or 3.3 volt ?
If 3.3 volt you'll need logic level translations between it and the 16F877( 5 volt only) OR pick a PIC from the xxxLFyyy series ( 3.3 volt types)
