Thanks Brian,

The T2400 is a constant from modedefs.bas that I've included in my program (though I have tried using 396 and various other modes as well).

I've had easy success using this type of comms before between a pair of 16F's (a serial LCD module for example) but the 18F doesn't seem to like it so I guess I've done something wrong in my code.

Is there anything tricky about using porte for serial comms?

The only other thing that might have an effect is I'm running the projects at different speeds but I've used defines in both to tell PBP the clock speed.

Regards
