This page demonstrates how a COM-to-TCP connection can be made from a to the.The first step is to install the Null-modem emulator (com0com) application, which installs and works as a driver for a pair (or many pairs) of virtual COM ports. You can download the com0com installer.You can create as many pairs of virtual COM port as you like, and use any pair to connect one application to another. The COM port pairs will be given names starting at CNCA0 and CNCB0. These names can be changed, but the default convention begins with “CNC,” followed by the A-B pairing, and the final digit at the end represents the number of the pair. All data sent from the “A” port will be mirrored on the “B” port of the same pair, and vice-versa.
