You may also want to consider some alternatives:

1. Use an 8032-derivative that has two serial ports.

2. If you're going to communicate with the other 8032 in a parallel fashion, you could also just communicate directly with the PC via the parallel port. That'd give you the added advantage of faster communication with the PC.

3. Communicate with the PC using your existing 8032 using bit-banging techniques. This means that you "manually" raise and lower a given pin to "clock out" each of the bits that you want to transfer. The PC will see this as a normal serial connection. This requires more overhead, especially on the receive side.
