Setting Permissions for a Program to open a port

Bitpim is kinda oneway, if it doesn't work - you're on your own.

I'd check if the module for the USB serial port is being loaded
properly, and whether there are any error messages in the output
of 'dmesg' regarding the device (whether it's the phone, or a
'smart' cable, as it was with my deceased Nokia).

Cheers,
Tink

I ran dmesg and got a boatload of listings, means nothing to me! How do I tell if the USB serial port is loading properly?

Code:

dmesg | grep -i serial
