I have the firmware upgrade that does DUN.

# sdpcontrol -a mytreo search DUN

Record Handle: 0x00010001
Service Class ID List:
        Dial-Up Networking (0x1103)
Protocol Descriptor List:
        L2CAP (0x0100)
        RFCOMM (0x0003)
                Protocol specific parameter #1: u/int8/bool 1

Here is what I use to connect to the net via the treo

rfcomm_pppd -a mytreo -c -C dun -d -l rfcomm-dialup

[mytreo has an entry in /etc/bluetooth/hosts]

My ppp.conf script is pretty much the same as yours (except
that right now I log everything but timer events).  From
ppp.log I see that the phone does not respond to the initial
AT<cr> with OK as it should.  So it seems the treo never
really sees any communicaiton.

Thanks for your response!
