I have followed the instructions that are detailed
below, and also tryed using kppp with no luck. Can
anyone give me some tips.

On my CMOS setting, I have no way of disabling my
COM2, but I did try just changing my serial port
designation in CMOS.

I can see the modem, when I do a cat /proc/pci

Anyway, here are some instructions I found online, but
haven't had luck with them.

After physically installing your PCI modem enter your
CMOS setup and disable COM2 (Serial Port Boot into
Linux and log in as root. Then run:

cat /proc/pci

Look at the output and locate the "bus" entry for your
modem. You need to locate the IRQ and the base I/O
address for the modem. Here is an example of the modem
output:

Non-prefetchable 32 bit memory at 0x00000000.

Bus 0, device 17, function 0:
Communication controller: Unknown vendor Unknown
device (rev 0).
Vendor id=1ac1. Device id=480.
Medium devsel. Fast back-to-back capable. IRQ 3.
Master Capable.
No bursts.
Min Gnt=252.Max Lat=14
Non-prefetchable 32 bit memory at 0xe4000000.
I/O at 0xb800 [0xb801]
Note in the output above the IRQ is 3 and the base I/O
is 0xb800. This is common for 56K PCI modem with COM2
disabled. Now link the modem to COM2 (/dev/ttyS1):

ln -s /dev/ttyS1 /dev/modem

Add this line to your /etc/rc.d/rc.local file using
the IRQ and base I/O address:

setserial /dev/modem uart 16550A port 0x6400 irq 11

Then run rc.local:

. /etc/rc.d/rc.local

You can test your modem by running "minicom" at the
command prompt. For example type ATDT18006381483 to
dial the phone number. The modem should dial this
number. "CTRL-A Q" will quit minicom.

thanks in advance,
