A: A null modem cable connects to two standard serial ports for networking two computers together. Null modem cables enable direct data transfer with minimum setup. Null modem cables reverse the transmit and receive lines on each end of the cable to enable direct two-way communication. A null modem cable for PCs ordinarily follows the RS-232 standard and uses the same serial ports as RS-232 cables.
