I have CMCON=%00000111 using porta.3 as serial input and it is working but when I swapped serial in to portb.2 and the switch to porta.3 thats where the trouble began. I have not changed CMCON=%00000111 at all just the tris for in/outputs, hmmm....and the switch when on goes to ground when closed and pulled high externally when open, that way the processor knows the switch is on or off.
