They are internal modems using an ISA slot. Unfortunately, I have to set this pc up to use dialup access so my options are limited.
To start with, you need to run
pnpdump to locate the ISA cards, and
create/setup an
/etc/isapnp.conf file. It's been a long time since I set one of these up; no ISA slots anymore. I would suggest opening
Konqueror, clicking on the
X in front of the
Location: bar, to clear it, then typing
man:isapnp in the bar. Read that page, then click the links at the bottom for
pnpdump and
isapnp.conf.
