Virtual Serial Port Driver is a commercial serial port emulator developed by Electronic Team. It is a professional-grade utility that creates pairs of virtual COM ports that can be connected with a virtual null modem. The virtual port pairs provide a communication bridge enabling data transmitted from an app at one end of the pair to be received immediately at the other end. This null modem emulator is a feature-rich solution to the problems caused by the lack of physical serial interfaces on modern computers.
