Our company produces software for large cruise ships; operating environments are ofter quite difficult to set up, so we do work with many subsystem simulator in order to make the very fists test & debug sessions. COM ports are real ports on our servers (when not replaced by Ethernet connections), but when it comes to perform small test (e.g. in smart-working), then a tool like Free Virtual Serial Ports is a very useful addon for building the test environment.

Without the need of the actual hardware, we can use this user friendly virtual serial port application to connect with virtual com ports and sniff the data communication. The tool is really robust and helpful.

I am ham radio and work a lot of digital communications, many receivers, decoders ... A virtual serial port handling tool is essential to link all the elements. After trying several programs, this is the one I liked the most.
