That is what it appears to be to us also, but the TRISC is configured as per
the directions in the data sheet which say RX and TX both should be set as
inputs (seems a little strange but....). Our main concern is why would it
work correctly with the emulator, but not with a regular chip. We even went
so far as to put a blank chip in the socket and still were not able to get
that line to drop low (the default TRIS is for input).

Thanks for the input though!
