The Virtual Serial Port Driver is a simple application that allows you to pair virtual COM ports. Virtual serial ports created in the virtual serial port driver behave as if they were real ports, so applications can communicate with each other and transmit data over the virtual null modem cable. Virtual serial ports created in the Virtual Serial Port Driver also support all serial port settings, strict baud rate emulation, HandFlow control, and signal lines.

Key features include:

• Create any number of virtual COM ports.
• Full emulation of real port settings.
• Management of all signal lines.

The virtual serial port driver has a user-friendly interface that allows you to quickly create serial ports with any name you want (you are not limited to COMx names). All in all, the application gives you many ways to personalize serial ports, and you can control them directly from your own application using vspdctl.dll. It provides reliable data transfer rates and allows you to test or debug any software or application you need to find any bugs in your code.
