Re: Puzzling Problem with Parallel Port -- Resolved
I appreciate the replies from people who offered help. While no
single reply hit my problem, the collective effort helped
considerably in narrowing my troubleshooting. Thanks.
When I re-compiled the kernel to include the parallel port, I didn't
realize I'd have to run update-modules to get the right information
in my conf.modules file. That's what it took.
Is this a newbie question? I don't know. I've been running Debian
Linux for over a year now. The fact that I don't know every detail
of Linux actually speaks well to the general effectiveness of the
distribution scheme. Apt and dselect generally get things to the
right place with a reasonable startup configuration.
