btw my 6103 also has similar ports on similar channels:

Record Handle: 0x00010000
Service Class ID List:
	Dial-Up Networking (0x1103)
	Generic Networking (0x1201)
Protocol Descriptor List:
	L2CAP (0x0100)
	RFCOMM (0x0003)
		Protocol specific parameter #1: u/int8/bool 1
Bluetooth Profile Descriptor List:
	Dial-Up Networking (0x1103) ver. 1.0
Service Name:
	"Dial-up networking"

Record Handle: 0x00010001
Service Class ID List:
	Serial Port (0x1101)
Protocol Descriptor List:
	L2CAP (0x0100)
	RFCOMM (0x0003)
		Protocol specific parameter #1: u/int8/bool 15
Service Name:
	"Nokia PC Suite"

Record Handle: 0x00010002
Service Class ID List:
	Serial Port (0x1101)
Protocol Descriptor List:
	L2CAP (0x0100)
	RFCOMM (0x0003)
		Protocol specific parameter #1: u/int8/bool 3
Service Name:
	"COM 1"

and I see that connecting to DUN gives me an AT command interpreter as
does SP on 3 (COM 1) but connecting to the SP on 15 (Nokia PC Suite)
doesn't. Thats using NetBSD though the program is not much different.

can you connect to channel 1 (Dialup Networking) with rfcomm_sppd?  That
should definitely take AT commands..

btw, didn't you say before that gnokii is supposed to be discarding "Nokia
PC Suite" ?  (actually, that was why I added the "Service Name" handling,
so I could see what my phone had :)
