can i use pin 3 (ATN) of the BS2 for serial communication with another
processor? It will only be receiving one bit. I've used all of the other I/O
pins as well as the TX/RX. if not, what can i do about this? thanks so much
for all responses

    If you are communicating with another processor using serin and/or serout,
    try using address on the processor. Using this procedure can let you
    communicate with a large number of peripheral processsors using only one
    Stamp I/O port.

    No. The ATN line is used to reset the BASIC Stamp (via programming
    interface) to start the download process -- it is not available for
    general-purpose or serial IO.
