What is a null modem cable?
A null modem cable is a cable which connects two computers directly. The connection is made using serial interface and actually requires no modem or phone line. These connections can be useful for some legacy applications, however due to the availability of low cost networking equipment null modem connections are now rarely used.
What is the purpose of a null modem cable?
A null modem is a cable connecting two serial ports with the input and outputs and device control lines crossed over, so the input pin on one port is connected to the output pin on the other, and so on. It is also called a 'cross-over cable'. A null modem allows two computers to be connected together using their serial ports without using modems (hence null modem). If you used a standard ('straight') serial cable, the two inputs would be connected together, and the two outputs, and so on, so the computers would not be able to communicate. Modems have their data and control pins reversed internally, so a 'straight' cable is used between a computer and a modem.
