I'm working on a BIOS for a Z80 computer. The only way to interface with the system is the serial interface. Unfortunately some features like the Xmodem support are very tricky to debug. There is no terminal software I have found that would log the complete communication between the remote device and the terminal software. I was already thinking about writing a minimal terminal software with this capability, but then I found Serial Port Monitor. AND IT WORKED OUT OF THE BOX. I had tried some similar software already but always met "cannot open port" issues. I know since X64 Windows serial port monitoring has become difficult - even Microsoft does not support their old Portman software anymore.
I haven't found a good free tool that will emulate a port and record/replay comms. So I chose the commercial option. I heard a lot of good things about Serial Port Monitor, which is a software port emulator. You can "connect" a physical serial port through it, so that your software uses the (monitored) virtual port, and forwards all traffic to/from a physical port. Very simple and easy to use!
Among all those COM-port monitoring apps I’ve ever test-driven, only Serial Port Monitor was both thoroughly reliable and simple to run. Plus, its interface is pretty self-explanatory, so I didn’t have to dig into some manuals to make the app work.

Putty and Screen are are garbage for working with serial, especially when you don't know the specification. Use RealTerm https://realterm.sourceforge.io/. Source: about 1 year ago
This is not really Labview stuff, but there's a nice little terminal program called Realterm I've been using whenever I need to decrypt unknown serial stuff. It's really nuts and bolts sort of a software and you can easily turn the message into binary or hexadecimal and flip all the control bits and all that neat stuff. Source: over 2 years ago
