3650 / BT / internet

Hello all,

I'm having problems trying to connect to the internet from my XP laptop via
a billionton bluetooth dongle through my nokia 3650.

I have paired the PC and phone successfully, but whenever i click on 'dial
up networking' in my bluetooth places, I get an error message saying "The
dial-up networking connection failed: Unknown port". I get the same message
if i try and connect any of the other services, including the BT serial
port.

Hunting around, I noticed that in the properties of my BT serial port, the
'Com port' drop window is balnk, and is blank when you open the list to
select a port.

Any ideas greatfully received.

Chris
