Gregory,

  There was a lot of time wasted playing with setserial because originally
thought it was a PCI device which would have meant isapnp was useless...
It sure didn't seem like 2 hours, but it took a while.

  The solution was since it's a ISA PnP card (not PCI) all that needed
to happen was the devices had to be enabled...
  (pnpdump -c > /etc/isapnp.conf; isapnp /etc/isapnp.conf) don't run that 
unless you want to wipe out whatever is there now.
  Then the kernel needed to be told what IRQ and such the device used 
(with setserial), but I think I setup the modem for a regular standard
IRQ and ioport... so that setserial wasn't needed.

  I thought the p account was deleted before you left.  The home directory
might not have been, but the account should have been.

  That directory should have had _nothing_ to do with the functioning of
your modem.  I would need to take a look at what is wrong...

  You need a 'z' added to the options list. '-xzvpf'

  Run the following (which are read-only commands and will not fix things),
and email the results to list.

=============
for l in /dev/ttyS*; do setserial -a $l; done

grep -vE '^#|^$' /etc/isapnp.conf

cat /proc/isapnp 

ls -l /etc/rc.boot
ls -l /etc/isapnp.conf
=============
