I'm looking for serial port monitoring software [closed]

On Windows machines, I've always used HyperTerminal (hypertrm.exe) to monitor serial ports. For my 32-bit Vista install, I copied over hypertrm.exe and hypertrm.dll from my old XP install and it worked just fine.

I don't have a 64-bit Windows 7 install, so I can't check that it would work for you. So it might need XP compatibility mode or some other 32-bit mode to work.

This person got it to work on Windows 7 32-bit. Also on that site is a list of more HyperTerminal replacements for Windows 7, though it focuses much more on the other communication protocols done by HyperTerminal.

Several other HyperTerminal replacement ideas are listed here.
