gnokii configuration for Nokia 6230i on Ubuntu 16.04

[Dan Lindfield]

Struggling to get gnokii to interface with my Nokia 6230i through USB Nokia cable. Got past the serial device "Permission Denied" by changing permissions "sudo chmod 777 /dev/ttyACM0" but then get either "Device or resource busy" or "Initialization failed (6) - Telephone interface init failed: Function or connection type not supported by the phone or by the phone driver". Can anyone help understand what is missing? Is it an issue with the cdc-acm driver and compatibility with phonet on my particular Ubuntu build?

gnokii --identify provides the following output:

1. [for connection = serial]
