I have a PCI modem - it's an IBM 33L4618
Is this supposed to be Linux-friendly? I haven't had time to try it yet but hope to in the coming days .....
Possibly not. But maybe :-)

IBM have excellent tech support on their website - feed the part number into the serach box for links to many more docs.
