baudrate

i'm going to connect between 16f877 and GPS EB-85A....
could someone help me...
i can't run this program...

'DEFINE HSER_RCSTA 90H
'DEFINE HSER_TXSTA 20H
'DEFINE HSER_BAUD 9600
'DEFINE HSER_SPBRG 25
DEFINE OSC 20
include"modedefs.bas"

pcout var portc.6 'Output to pc
pcin var portc.7 'Input from pc
gpsin var portb.2 'input from gps
gpsout var portb.1 'output to gps

gps_dat var byte
a var byte

for a = 0 to 41 step 1
lookup a,["$PMTK314,1,1,1,1,1,5,1,1,1,1,1,1,0,1,1,1,1"],gps_dat
SEROUT gpsout,T9600,[gps_dat] 'send pmtk to gps">command tok baudrate gps'

next a
pause 100

main:
serin gpsin,T9600,100,cont,[gps_dat]
cont:

SEROUT pcout,T9600,[gps_dat] 'send nmea to pc
'serout pcout,T9600,["rt",13]
goto main
end

any idea please....:(

These Defines are used With HSEROUT and HSERIN and not any other serin type commands

DEFINE OSC 20
include"modedefs.bas"

pcout var portc.6 'Output to pc
pcin var portc.7 'Input from pc
gpsin var portb.2 'input from gps
gpsout var portb.1 'output to gps

gps_dat var byte
a var byte

for a = 0 to 41 step 1
lookup a,["$PMTK314,1,1,1,1,1,5,1,1,1,1,1,1,0,1,1,1,1"],gps_dat
SEROUT gpsout,T9600,[gps_dat] 'send pmtk to gps">command tok baudrate gps'
What are you hoping to accomplish here? Exactly. 
next a
pause 100
What it will do is send out those characters in ASCII
main:
serin gpsin,T9600,100,cont,[gps_dat]
cont:

SEROUT pcout,T9600,[gps_dat] 'send nmea to pc
'serout pcout,T9600,["rt",13]
goto main
end

any idea please....:(

Your serout pcout will send 1 byte stored in gps_dat and then the STRING rt
So yeah, I have some ideas, you need to explain what you want this to do and what does / does not work, and we will help you.

Edit : didn't see the apostrophe '.

i'm doing for my project....
title : Positioning and navigation using GPS....
using PIC microcontroller to interface with GPS...
in this project i'm using Etek EB-85A module sensor...
Does anyone hv any idea on how to do the command so that i can run the program?....

Flow >> 1) GPS detect from satellite >>2)send data to PIC microcontroller >>
>>3) view result at serial communicator from microCode studio.
