First off, as of the date of writing this there is a bug in
Slackware 11 and the `scanModem' script will not run successfully. I have
made Patrick Volkerding aware of this and he tells me he is working on a
fix.
# ./scanModem
From http://linmodems.technion.ac.il , get a recent update of scanModem,
if this copy was not there obtained. There are weekly updates.
Updated on: 2007_March_15
./scanModem: line 3595: unexpected EOF while looking for matching ``'
./scanModem: line 5311: syntax error: unexpected end of file
This is a problem with Slackware 11, not the `scanModem' script,
and, unsurprisingly, causes other problems. Anyone using Slackware 11
beware that bash and sed (at least) do not behave as might reasonably be
expected. (I feel I should advise that anyone new to Linux and having
problems configuring their computer should not use Slackware 11 until they
are in a position to understand the implications of this problem, or a fix
appears and you have applied it.)
As at this writing, Slackware 12 will be using the 2.6.18 kernel,
which gives the same results as the 2.6.20.2 kernel compilation effort
listed below. So, Slackware woes aside, it looks to me like the latest
kernels require changes in martian. Am I correct, and if so what can be
done about it?
Given the fixes to ACPI that have made their way into late-model
kernels, I'm not enthusiastic about retrofitting an early model 2.6 kernel
to get the modem to work (and it will still be broken for Slackware 12
which has already in the development tree, I'm assured, fixed the bash and
sed bug) and I'm hoping the martian source can be modified to accommodate
late-model kernels. Output of a compilation effort below.

Doomsday device? I suppose I could part with one and still be feared.
