    Appendix B. Null-Modem Cable A null-modem cable allows communication between two similar devices. It is sometimes called a crossover cable, because the transmit and receive lines are crossed so that the two devices can communicate. An RS-232 null modem cable usually also crosses other handshaking lines. An RS-232 null-modem cable can be purchased at a local computer store.
