Hi Peter,

> here are the results. I was successful, when I removed link_key again.

I don't what is with the link key. Still weird that they request
authentication on the SDP search, but not using security mode 3.

So they are using LAN access using PPP and not the Dialup Networking
profile. Even if the name is somekind misleading you must use dund for
the connection. Maybe this one does this right job:

dund -n -D -P 1 -X 00:0B:CE:00:01:8F

If not then your must send in the hcidump and hope that someone decodes
the PPP problems. Using PAN would be a lot easier.
