I am a former Motorola employee at the facility that designed and
manufactured the modem in question (a business which Motorola has since
gotten out of). I''ve got an external version at the house.
Unfortunately, the BEST answer would be to disable Plug-N-Pray. But that
modem was probably the first Plug-N-Play modem that Motorola put out,
and the stupid decision was made to not include the ability to configure
the modem via jumpers. Later (cheaper) PNP modems did have jumpers...
To quote the FAQ on the modem (at
http://www.mot.com/MIMS/ISG/Products/lifestyle288internal/faqs.html):

I wish I could help you, but I don't have an internal version of that
modem to test here at the house - I've got the external version. I
tried the PNP stuff under Linux with one several years ago, but the
isapnptools were sorta immature at the time.
Another issue you should be aware of with the Lifestyle 28.8 is this. It
is an EXCELLENT modem, with the guts of it being the Motorola "D" chip -
a combination of a 68020 and a DSP on one die... that said, probably
1/4 of the Lifestyle 28.8's that shipped had buggy software. They would
have random hangups and protocol errors. The bug was in the LAP-M
protocol handling, and the only solution if you have a modem with that
problem is to turn off LAP-M via an AT command, or replace the firmware
(impossible now - its a soldered prom, and the factory is no longer in
business)....
Hope you get it working.
