I've looked all over, and can't find the answer on my own, so I'm asking 
the smartest bunch of people I know.
I'm using Windows XP, and can't use one of the serial ports.  I'm trying 
to install a drawing tablet that uses the serial port, but now matter 
what I try (Hyper Terminal, Tera Term, PortMon, other programs that use 
the serial port), nothing can use it.  The error message I get says that 
something else is using the telephony device.  Is there any way I can 
tell what process is using the serial port?  I've tried Googling.  About 
the closest thing I've found is a Microsoft utility called PortMon, but 
even that can't attach to the serial port and won't/can't tell me what 
is using it.
I don't know if the serial port has ever worked properly on this PC.
I've checked BIOS settings for the port.  Is there any possibility that 
Norton Internet Security is doing something?

Thanks,
John Pfaff
