Replacing existing pic

[Freman]

I'm not actually using the serial at the moment, I'm just trying to get to the "other" part of the code, but I'll try 2400 bps, I'll also try the osccal

So you're telling me I should set that bit to 0 in my code?


Nope still no go This is the code and attached is the schematic

I know the slave is bringing the pins high (multi-meter and beep confirms it)

Edit: One clue I have is.... if I comment out the serial routine and tell it to goto the 'testSlave' label, it works fine
