TP 600 modem issues

I'm using an IBM TP 600 loaded with RH 8.0 (2.4.20) and am currently trying to get the internal modem to work. Yep, I'm aware that it can be a pain, but I think I am very close....

1. I compiled the kernel with the mwave support (not as a module).
2. I ran `setserial /dev/ttyS1 autoconfig` as suggested on the IBM developer's site where the mwave drivers are available. Following that, /dev/ttyS1 is set to:

/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3

3. I soft-linked /dev/modem to /dev/ttyS1 for ease.
4. I ran kppp and get "modem busy". Same results for running a test against the modem with any modem based connection program (kermit, minicom, etc).
5. syslogs show no anomalies whatsoever.

Any ideas? Here is the output of /proc interrupts:
0: 182850 XT-PIC timer
1: 2277 XT-PIC keyboard
2: 0 XT-PIC cascade
3: 0 XT-PIC mwave_3780i
9: 3501 XT-PIC 3c589_cs
11: 0 XT-PIC Texas Instruments PCI1250, Texas Instruments PCI1250 (#2)
12: 21102 XT-PIC PS/2 Mouse
14: 13233 XT-PIC ide0
NMI: 0
