Greetings all :-)

I'm having a bit of difficulty configuring my 3com 3CCM556 Cellular modem.  I 
really only want to use the regular modem for ppp but I can't seem to figure 
out how to get it up and running.

It's detected by pccard, originally it came up as sio4:

Mar 23 08:07:30 foobar /kernel: sio4 at port 0x2e8-0x2ef irq 3 slot 0 on 
pccard0
Mar 23 08:07:30 foobar /kernel: sio4: type 16550A
Mar 23 08:07:30 foobar pccardd[55]: sio4: 3Com (3CXM/3CCM556) inserted.

Then in my reading, I determined this was likely a multi-port card as it came 
up on sio4 so I added the appropriate items to my kernel as per the FAQ:
options         COM_MULTIPORT

device          sio4    at isa? port 0x2a0 flags 0x701
device          sio5    at isa? port 0x2a8 flags 0x701
device          sio6    at isa? port 0x2b0 flags 0x701
device          sio7    at isa? port 0x2b8 flags 0x701 irq 12

Now the card comes up on sio8:
Mar 23 21:21:57 foobar /kernel: sio8 at port 0x2e8-0x2ef irq 3 slot 0 on 
pccard0
Mar 23 21:21:57 foobar /kernel: sio8: type 16550A
Mar 23 21:21:57 foobar pccardd[55]: sio8: 3Com (3CXM/3CCM556) inserted.

So my question is simple: What am I doing wrong? :-)  I guess what I don't 
understand is how does the serial port (sio) translate to a usable "COM" port 
like /dev/cuaax?  

Any pointers would be greatly appreciated! Nothing pains me more than having 
to boot my windoze side to dial-up while on the road ;-)
