>From the driver installation instructions (with latest downloaded drivers):

"Some versions of Windows, and some drivers, will allow the user to change some 
of
the settings for the new ports, while other versions will not. Things that might 
be
able to be changed are: The port number (COM5>>COM2 for example)..."

In my XP installation, I had com1 and com2 on the motherboard, and a modem on 
com3.
The new ports were automatically assigned coms 4,5,6 and 7. In device 
manager/ports/
properties/port settings/advanced, you can reassign the port assignment to any 
unused
com port between com 1 and com 256. I reassigned com 7 temporarily to com 8, and 
the
new assignment registered ok in device manager. I didn't test it.
