A communication protocol

We were interested in designing a communication protocol which can be used to tranfer files between personal computers. We have made a cable which connects the parallel ports, and is able to transfer 2 bits in either direction (instructions in the paper). Using this facility as a primitive, we designed protocols to establish the connection, and protocols to transfer data from one machine to the other. Our protocols did not use any timing, are stable, and extremely reliable.
