permissions on the /dev/ttyS15 device- maybe you should change the group
on the file to something else (you can try "users", "nobody", and "root"
for example).

If the above doesn't work then you might try checkin the mknod parameters.
I know that the 'c' parameter is fine since the device is a character
device. However, the major and minor numbers on the device are unfamiliar
to me.

To determine if the module has completed loading do 'lsmod'. It
should mention the pctel module then.

To find out where the PCI card is located in memory and on the PCI bus,
you can usually look through /proc/pci . You will be looking for a string
that says something like 'communications controller'.

If you think it necessary, I can explain what UUCP is, describe what major
and minor numbers do for device nodes (mknod stuff), etc- but it shouldn't
be necessary to know in order to get your linmodem working. Unfortunately,
I doubt I can be much more helpfull. If you still have problems... maybe
someone else on the list here has some suggestions (shrug).

 Best of luck.
