null modem cable

An RS-232 cable used to connect two computers in close proximity for file transfer. It attaches to the serial ports of both machines and simulates what would occur naturally if modems and the phone system were used. It crosses the sending wire with the receiving wire. A counterpart special cable is also available that uses the parallel port for higher transfer speed. See LapLink cable.
