Well. Almost. I got further. The PIN authentication worked and the key
is saved in /etc/bluetooth. However, minicom and pppd still don't
quite work. Here's what I get from minicom:

arthur:/home/khaberz# minicom
minicom: cannot open /dev/rfcomm0: No such file or directory

It's there of course:

arthur:/home/khaberz# ls -l /dev/rfcomm0
crw-rw---- 1 root dialout 216, 0 Nov 18 19:48 /dev/rfcomm0

This is in the syslog:

Nov 19 18:11:38 arthur kernel: hci_cmd_task: hci0 command tx timeout

The output of hcidump -X while starting minicom is attached.

Thanks!
Kai
