[A. Andria]

Hi,

Is there any body had an experience using gnokii+Nokia 3120+DKU-5 under 
Ubuntu 5.10 ?

I'm trying to connecting Nokia 3120 with DKU-5 Cable using gnokii.

My ~/.gnokiirc config is :
================
port = /dev/ttyS0
model = 6510
connection = dlr3p

The Output is :
================

What's wrong with my gnokiirc. How to get IMEI and Model ?
How to check if my DKU-5 cable is working ? What is the correct port ?
I don't know the step. Any help would be appreciated.
