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.

In addition to allowing a virtual null modem connection, our RS232 emulator can also assign custom names to serial ports. It does not have limits on virtual port creation as well, with the only limit being your system resources. As a virtual serial port emulator, VSPD transfers data between connected ports almost instantly, and with none of the factors that could affect a physical cable. An SDK is available as well, allowing the port emulation features to be added to commercial projects.

Features Offered by Virtual Serial Port Driver

Find out what makes this serial port emulator practical, convenient, and fast. VSPD has numerous advantages both over similar software and over physical null-modem connections.

Multiple virtual ports

This virtual serial port emulator has no limits on the amount of created ports, outside of your hardware. Virtual ports can be accessed from the Control Panel, with separate access rights for each port.

Flexible options

Split and join serial ports, form bundles, and create automatic switchers. Configure the COM port emulator to fit any possible use.

Efficient communication

Achieve a fast and error-free connection that’s only possible with a null modem emulator. No cables or adapters are required.

Virtual Serial Port Driver vs. Null-modem emulator

VSPD and the com0com Windows virtual COM port emulator have differences outside of licensing. Many of these are related to working on modern systems, co-existing with connected physical devices, creating presets, and various other features that can be important in the workplace.

What problem can be solved with a Virtual Null Modem?

Some programs can only communicate between themselves over a serial connection. If you have two such programs on the same computer, then you can connect them with a COM port emulator. By creating virtual ports for the applications to use, they can be connected directly on the system, without the need for physical cables. This is called null-modem emulation, and we’ll compare two virtual serial ports emulators that have this functionality.
