Problem displaying data from GPS module & using 16f877a

[financecatalyst]

If the GPS works connected to a PC, it means its output is inverted.

You need to modify your

serin2 portc.4,4800,[WAIT("$GPRMC"),STR sms\35]

Reread the manual for SerIn2 - your mode value is incorrect.

Thanks for the input but could you help me advising what baud should I use, I am little confused about this. The datasheet of the module does says 4800 is default (Datasheet attached) and manual also has only one option for 4800 baud.

I also want to say that I connected the gps module via MAX232 to the PC.Thanks
