Problem displaying data from GPS module & using 16f877a

[aratti]

serin2 portc.4,baud1,[WAIT("$GPRMC"),STR sms\35]

Which is the value of baud1?

When you use wait string, remember that they are case sensitive "$GPRMC" is different from "$gprmc"

I already suggested you, in another thread, to use a timeout sequence. Your serin2 instruction will wait for the identifier and then it will wait for a string of 35 characters. If your GPRS will send only 34, serin2 will remain there waiting forever.

One turn around is the use of the timeout:

GPRSLoop:
sms[0]=0
serin2 portc.4,baud1,500,GPRSTest,[WAIT("$GPRMC"),STR sms\35]
GPRSTest:
If sms[0]<>0 then goto label ??     ' here you check byte[0] for data presence 
goto GPRSLoop
