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?

You can use Process Monitor from Sysinternals

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

    It doesn't work for 64bit OSs.
