Ive just bought a CA-42 cable for my 3100, and also installed the nokia pc suite application, it all works fine and there is no problem there.
The thing is im trying to develop a small java application that takes messages off the phone and processes them. To do this i needed to disable the connection between the USB port and the nokia pc suite, there by allowing me to contact the phone through my own devices. The trouble is now i cannot contact the phone even through hyperterminal using AT commands.

Is the 3100 configured to only allow itself to be contacted by a nokia application?or does it just no support AT commands?
Any help????
