Hi Peter,

Indeed, that's exactly what's happening.

Ah. It seems that there's been quite some change in the code base of the
option driver. Using .33.3 here. No such thing as "blacklisting".

For the olicard100 it's been port 2, dialling, pppd starting up, but lcp
cfg req timeouts. At least with the olicard100 there's been no real dialup.
Conn endpoint has never been talking to the device..

Thanks alot for your hint. Previously I intended to wait for the .34 to
come out, but regarding the promising changes in option.c I will reconÑider this.
What are your overall xp with .34 so far? rc-7 is out, quite a rc count.. Maybe
the .34 is also levelling out these days.. :)

Cheers,

Nils
