Then may I ask how XP does it? I have to dual boot between XP and Fedora.
When I go into XP's device manager I see all of the appropriate hardware
listed, no extra serial ports. When I boot into Fedora and go into /dev, I
see the same hardware except I have 32 serial ports and 64 tty nodes (tty is
for virtual terminals right?). How can 1 OS show the correct number and
another show the wrong number? I ask so I can better understand what is
going on.

Thanks,
