[techtalk] For the not so techie Linux users

[kev]

Thanks Norma,
I've had Red Hat 6 on my machine at home for a few months, and still haven't
got my modem working :-(
My investigations, which have been conducted at a less than leisurely rate
because I have so many other things to sort out, have led me to believe that my
IRQ level may be wrong. The modem dials the ISP ok (but things move very very
slowly), has a little chat then the ISP hangs up and errors appear in
/var/log/messages. The next step of my investigation was to find out how to
change the IRQ levels, so hopefully you've just solved one of my biggest Linux
problems for me :-)
I'll try this tonight when I get home. I do some work at home, and I've been
getting by by connecting to my work machine with an ssh client on Windows, but
if this works then I should really have no more reason to use any Microsloth
products any more :o)

Many thanks,

- Kev
