is this all the pic is going to do?
if you are going to do the display mux with the pic, then MOST of the time
the pic will be in delay loops. use these loops to check for the serial data
start bit then go off and receive the data. the amount of time it takes to
receive the data will not effect the display. if you have problems seeing
the start bit and getting to the receive routine you could send a dummy (hex
00) character before the serial number and ignore this character in the pic.
