It does detect serial ports found in the machine.
However, it _always_ offers the configured number of serial devices.
This is to allow folk whose ports are not autodetected to configure
them appropriately via the setserial command. If they were not
available, they could not configure them.
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,
Jason
