Nokia 6020 over IrDA on WinXP - Couldn't open PHONET device: No error

[Mike]

Hello Experts,

I am trying to connect to my  Nokia 6020 on WinNT over infrared. I tried
the binary gnokii-0.6.14-win32.zip on both a destop with Ir-stick on USB
and a native IR-device on my notebook. The IrDA in both environments
work fine with the Nokia PC-Suite as well as with a synchronizing
software called winfonie2. So the hardware must be OK.

But I cannot get Gnokii connecting. I tried all possible COM1 to COM9
and some Baudrates without success. The file gnokii-errors is created
but emty. Here is the complete command log:

...\Gnokii>gnokii --identify

Couldn't open PHONET device: No error

What can I do to overcome the message "Couldn't open PHONET device: No
error"?

Thank you for your help!
Mike.
