Two weeks ago i posted a question about ISDN-Drivers.

I regret but there were only questions of people that wanted
to know the same thing. I did the same posting in <comp.os.linux>
and got the same result. (It seems that there isn't anything in that
way of freeware.)

The only one who is likely to do something is Matthias Urlichs. Therefore
i'll post a part of an article he wrote in <comp.os.linux>:

If somebody knows more than i do please post a followup - i think
that there are many people interested in these problems.

Thanks ,
