looks fine to me

good

good

why are you using sdptool? there is nothing wrong with it, but FreeBSD 
5.3 has its own sdp server (sdpd(8)) and client (sdpcontrol(8)).

again why sdptool? in 5.3 rfcommm_pppd(8) should register LAN service 
automatically with local sdpd(8).

looks fine to me. i do not think you need "open"

just by looking at hcidump i can see that remote side has terminated the 
connection. i do not think this is the bluetooth related issue. most 
likely this is ppp related issue.

ah, i see you already figured it out. i was just about to suggest you to 
check for ras :)

btw, if you had used "hcidump -X" or "hcidump -A" you would have noticed 
that right away :)

also how did you manage to start rfcomm_pppd(8)? it should exit if it 
cant register service with local sdpd(8). i do not see you mentioned 
sdpd(8) anywhere.

so, is everything works now?
