[Interest] Is there a way to simulate serial port data?

[Stéphane Fabry]

You can also simulate via external software like https://docklight.de/

or create serial port pairs (search for virtual serial port)

Right now I'm chasing down a bug that has only affected us a dozen times or so over 3 years, so it's tough to justify ripping up all of the serial port stuff right now, but it needs to be done at some point. But for the short term, I was hoping I could find a way to simulate data coming in on the serial port so that I can concentrate on the existing bug, without modifying the existing codebase.
