I've added 'modedefs.bas' and set mode '0' still no joy

 CMCON0 = %00000111 
ANSEL = %00000000 
TRISIO = %00000000 
GPIO = %00000000
 
DEFINE SER2_BITS 8

INCLUDE "modedefs.bas"

MYVAR  VAR BYTE 
 
MAIN

pause250

serin2 GPIO.0, 0, [DEC MYVAR]

IF MYVAR = 3 THEN HIGH GPIO.5
PAUSE 250
GOTO MAIN

But if GPIO.0 is connected to the POT it may not work.

Hi mackrackit

I've metered GPIO.0 out to the pot, it does seem to be connected(getting some strange readings though).

I then changed the cable from GPIO.0 to GPIO.4 (and the program to reflect the change) when I send from the serial communicator two LED's briefly flash on then off ( pretty quick though).

I increased the pause time from 250 to 2000, still only a brief flash but definately
flashing!

Two LEDs ???

GPIO.4 is connected to a LED ?

If you have a 14 pin chip try it. I think some of the pins from a 14 will go directly to the J3 header.

Making progress though!!!

Hi mackrackit

Was getting there, I say was because every time I try and load a program now 'checksum verify failed' appears.Any ideas on that one.

Disconnect the serial cable from the PC?

Cured 10-10 mackrackit

I'll change chips in a mo'
