Design of a point to point serial communication system A sends P0 and P1 port switch data, B receives and were displayed in the P0 and P1 LED lights on. Note: The two machines communicate using serial mode 2, the baud rate doubling (or two machines using serial communication mode, baud rate is 19.2kbit/s) A machine sends a query, B machine uses interrupt reception. Design the appropriate hardware and software to achieve 485
Plus send and receive both the CRC
