I need to listen to everything that goes (both directions) through a virtual serial port on Windows 7 64bit.

I do not need to send anything, just monitor the communication for debugging purposes.

How can I do that?

Old question but still actual. There are many applications that can monitor serial port. But only several are supported on Win7 x64, Win8. I also faced this problem. And i founded a good soft - Eltima serial port monitor works on Win7 x64.

Don't take this the wrong way but I see you have linked the same website in both of your answers. If you are affiliated to that website in any way and you don't declare it you might find your posts tagged as spam. –  Tog Oct 11 '13 at 9:48

You can use Process Monitor [1] from sysinternals (now bought by Microsoft).

It allows to see all reads and writes made by a process.

It doesn't work for 64bit OSs. –  jlafay Dec 20 '11 at 15:07
