Hi, I was happy when I got the GPS set to 9600 but yesterday I found out that it reset itself to 57600. I tried to reset it back to 9600 but failed and I tried it the whole afternoon...I use this as my reference http://www.laptopgpsworld.com/3701-d...ocosys-ls20031 it can only lowered to 38400, so I have no choice but to try this baudrate. My first time to use 20Mz crystal. I'm showing my codes when the GPS was running fine in 9600 baudrate. Please forgive my codings, still learning
Code:
clear
Include "modedefs.bas"  
H VAR BYTE[2] 

TRISD = %00000000 ' PortD.0 LCD connection
TRISC = %10000000 ' PortC.6 as tx and PortC.7 as rx
TRISB = %00000001	' PortB.0 as rx from GPS
PortB =  %00000000 
PortD =  %00000000

Please help me make it run to 38400 baudrate, I have the 20Mz crystal.

thanks in advance,
