Trying to get bluetooth running under Debian Testing here. Connecting
to my device (Nokia 6600 cell) works fine, but whenever I try to
access the device using pppd or minicom I get something like this:

Nov 19 06:18:01 arthur pppd[1382]: Failed to open /dev/rfcomm0:
Invalid argument

Yes, I did see the FAQ, but the rfcomm connect doesn't help either.

Here's what I do have working:

arthur:/home/khaberz# rfcomm show

Any help is greatly appreciated.

Thanks,
