You can use the program "Handle" for debugging serial ports.
For example, on this computer, I have a modem on COM3 and the UPS
shutdown interface is on COM4. COM3 and COM4 are USB to Serial adapters.
In Handle, I can see
94: Thread ups.exe(252): 288
98: File (---) \Device\VCP0
D4: Thread hypertrm.exe(3192): 2084
120: File (---) \Device\VCP1
I'm using WinXP right now, and I used the built-in HyperTerminal program
to make the modem "busy", for the purposes of this test.
The VCP part, stands for "Virtual COM Port", a feature of the
FTDI serial chip driver.
On a computer with a "real" serial port, where the serial port is on
the I/O plate on the back of the computer, and it is hosted by the
SuperI/O chip, you might see
hypertrm.exe pid: 1904 108: \Device\Serial0
Now, Windows 7 could be using yet another naming convention, which
is why using Handle is so much fun. "Handle" is a command line program.
On Windows 7, I'd type cmd.exe in the Start box, then right click
and "Run as Administrator", and once the Window appears, cd
(change directory) to the directory with the program, then type
handle -a > handle_out.txt and have a look at handle_out.txt with
Notepad.

It's probably Windows FAX and Scan doing it, but it would be
fun to confirm that.
My track record on figuring this out, is pretty poor, even
with Handle in my possession. I've spent hours staring
at that output, trying to figure out where the serial port
went :-)
Once the serial port is free (i.e. no program "owns it"), it
should disappear from the Handle output, and then you'd expect
the new FAX program to detect it and grab it.
