CMUcam communication problems

Archiver

I seem to be having problems with getting a CMU cam to communicate
with BoeBot. I have connected the wires according to the
documentation, transmit on pin 10 and receive on pin9 but for some
reason the program stalls on serin 9,240,[noparse][[/noparse]WAIT (":")] Anyone have
any ideas that could be causing this. I have the whole code below as
it isn't long and is part of the initial checks. The documentation
says something about installing jumper 2 and 3 but I have no clue
what they are talking about. I found jumper 2 on the camera board
but I can't find jumper 3.
