I have this odd problem here, I have two phones 6670 and 6610. When I try to connect to my pc with my nokia 6670 and try to add outgoing com port there my computer just gives me the message that the device don't support serial port, contrary when It shows me the other phone 6610 with its serial port.

it loooks like my 6670 only supports DUN. Can someone tell me why is that? Is there any way to use my serial port ?

TIA
