The title questions pretty much says it all. I've looked around quite a bit, but I have yet to find a free way to monitor a serial port (without opening or blocking it from other applications), that works on Windows 7 64-bit. Even Microsoft's own portmon does not work. A few posts have talked about running it in compatibility mode, but it doesn't work for me. I've tried compatibility mode for Windows XP service pack 2 and 3 (the only ones available on the drop-down list), and neither allow it to function.
So yeah, is there any FREEWARE licensed serial port monitoring software out there for Windows 7 64-bit?
