This is from memory (I race N2 now, but it should be
simular in N1).
1. You should have a free COM port on each computer.
2. Get a "Null Modem Cable" from you local computer store
(Future Shop or whatever). Make sure you by a cable
with the proper sized ends -- 9 pins or 25 pins.
3. Hook up the cable
4. Start Nascar
5. Setup the serial port and speed to 9600 baud on each machine.
6. Race.
