BlueZ on Zaurus and PAN to windows XP with widicomm s/w

Hi, I have a Zaurus SL-5500 running the tkc ROM with included bluez
bluetooth stack. The CF card is recognised as a Mavin Bluetooth CF
card.

I have tried making a PAN connection but keep getting disconnected
before I get going with the following error:

Connection refused[111]

I did try tech support for Widicomm who cryptically told me from the
trace I sent them that the PSM value being used was not correct.

Can anyone help someone who knows little about linux to reconfigure
and get working please?
