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?

PortMon from MS/Sysinternals would not work because the driver depends on the bitness of the OS. Unlike with usermode programs which can use WOW64 to run a 32bit app on a x64 system. –  0xC0000022L Jun 2 '12 at 0:00

I just tried Advanced Serial Port Monitor "Spy" mode does just what you want. It's only free to try, however, you have to pay for a permanent solution. http://www.aggsoft.com/serial-port-monitor.htm

A work around I have used in the past when I was in the exact same situation as you was to use a 32 bit VM.

It's not the greatest solution but it does work and has no cost (other than any costs associated in setting up your VM Environment)
