As a result, your communication application interacts with these ports in exactly the same way as it does with the hardware ones. Each virtual COM port exactly emulates parameters and behavior of physical serial ports. It also allows the use of named pipe technology to connect the created port to a serial application or virtual serial device. Our freeware virtual serial port tools kit allows you to create virtual COM ports and connect them into pairs using software-based virtual null-modem cables. Free Virtual Serial Ports is a software COM port emulation utility for Windows platform.
