    I do not know if micro (u) can, but ....

    well, who knows. It could be your PIG code or your '51 code or your connections. AH, just remember - becuse of identical names, most routing software tend to connect Tx to Tx instead if Tx to Rx, YES, I got caught on that one once :(.

    "it does not work, help" is NOT a substitute for debugging although it seems many believe so.
