Ok, at this point it looks like something else is using the the device
ttyS1. What's running on pid 8388? Try "ps aux | grep 8388"

Good.

It looks like there is already a device at 2f8. I mentioned in one of these
modem related threads that most computers already have two serial ports
(ttyS0 and ttyS1) built in so internal modems usually have to go on ttyS2 or
ttyS3 (using addresses 3e8 or 2e8). It looks like you just confirmed that
this is the case for you.

0x0100 is a pretty wierd address to use for a serial port. You can
sometimes get away with using unusual addresses but it's asking for trouble
later unless you know what your doing. I highly recomend you use one of the
standard configurations for an internal modem such as:
ttyS2 3e8 irq 4
ttyS3 2e8 irq 3
Once you've set the correct info in isapnp.conf you'll need to make sure
your 0setserial file matches.

Normally kerneld loads modules such as ppp automatically so you "shouldn't"
need to modprobe it but.... After you modprobe ppp do you get an error?
Type "dmesg" and examine the last few messages. After you run pon, try
running "lsmod" to see the list of modules installed.
If you put "ppp" in your /etc/modules file it's get loaded at bootup and
stay loaded but if you can't load it manually then something's wrong.

Not too long at all, it's exactly the stuff we need to make this work.
