Virtual Serial Port Driver

The main goal of the Virtual Serial Port Driver is to create virtual COM port pairs. Virtual serial ports created in VSPD behave as if they were real ports and are treated as real with serial applications. Through these ports, serial applications can communicate with each other and transfer data using a virtual null-modem. Data written to one virtual serial port can be instantly read from the other. The virtual serial ports created in VSPD support all serial port settings, strict baud rates, HandFlow control, and signal lines. Once a pair of virtual COM ports is created, these ports appear in Device Manager. In addition, these ports are available automatically at system startup, even before logging in.

Virtual Serial Port Driver is available in a GUI version.
