Free Serial Protocol Analyzers?

I need a lightweight serial protocol analyzer that will let me see what's happening on an RS-232 line, or at least a terminal program that will let me capture images from a serial stream. I've seen such things pass before my eyes, used by colleagues, but I've never needed one myself.

Any recommendations? I'm running Windows XP, and getting by in Cygwin with cat /dev/ttyS0 > file.txt. It's adequate, but barely.

Here's some free DOS analyzers:

Hopefully you can make a DOS boot floppy or CD and run off of that instead of Win.

If you go to sysinternals.com

you can download portmon which, from a Windows system, lets you monitor and log I/O to the serial (or parallel) ports. I've found it very useful, in the past, for analysing serial communication problems.

I once wrote a Windows application to monitor 5 serial channels. To be found at :

I've been quite pleased with ComLite32. You can use it to monitor a COM port that a Windoze app is using, or you can "pass-through" the Windoze PC to monitor two external devices communicating with each other. You can't use it as a terminal, and I haven't tried it on XP yet.
