Parallel Port Communications
Set up a hardware and software protocol for communicating between two computers using their parallel ports. Note that you only have the five status lines for input. In order to send a byte, you should break it into two 4-bit "nibbles", and send four bits at a time. The fifth status line should be used for handshaking. The sending computer should indicate on the handshaking line that it has data to send; the receiving computer should acknowledge receipt of the data and tell the sending computer it is ready for the next "nibble".
