Virtual COM Port Emulation Tools for Radio Control
Find software applications that create virtual serial ports to connect ham radio programs and devices.
Many ham radio operators use virtual serial ports to connect their logging software, rig control programs, and digital mode applications. These virtual ports allow different software to communicate with each other, or with physical transceivers and other station hardware, over a network or within the same computer. This setup is especially useful for complex stations where multiple programs need access to a single radio or when operating remotely.
Operators often rely on virtual serial port drivers, such as HW VSP3 or VSPE, to create these software-defined COM ports. These tools can emulate physical serial port behavior, allowing programs to exchange data as if connected by a null-modem cable. Some applications, like VSP Manager, are specifically designed to help hams link their rig control software using CAT commands, streamlining station operation and enabling advanced digital modes like FT8.

The Null-modem emulator is an open source kernel-mode virtual serial port driver for Windows, available freely under GPL license.Allows you to create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. -
Windows user-mode application, which allows you to create software virtual serial ports and emulate physical serial ports behavior. It operates exclusively in user-mode, therefore it is more stable and uses less memory, processor and operating system resources than any competitive products. -
HW VSP is a free software driver that adds a virtual serial port (e.g. COM5) to the operating system and redirects the data from this port via a TCP/IP network to another hardware interface -
Software to create virtual com ports when you need to assing different serial ports and you have just one COM port on your PC. Commercial version -
VSP Manager is a software program that creates serial port pairs which allows software programs to talk to each other using Cat commands. This virtual com port emulator is offered FREE to Ham Radio Operators. -
Virtual Serial Ports Emulator for Windows. Virtual Serial Ports Emulator tool (and VSPE API) is free on 32 bit platform and can be used with no charge for any purpose. No registration or activation key is required.
