when I design the PCB I used the PortB.5 with a 20Mhz crystal with bigger pcb foot print 46x17mm
then I decided to lower the parts count and the PCB foot print...
1. How can you be sure that the receiving PIC will start "listening" just before the sending PIC? Better use a start character on the sender and use this character as a WAIT one on the receiving PIC...
