Heres my gnokiirc:

[global]
port = /dev/ttyUSB0
model = 6510
connection = dlr3p
use_locking = no

[logging]
debug = on
xdebug = on

Manually binding the device:

# insmod /lib/modules/2.6.13-1.1532_FC4/kernel/drivers/usb/serial/ 
usbserial.ko vendor=0x10ac product=0x10c6

I've tried with and without the pl2303 but nothing seems to happen,  
and I get the following response from gnokii...

# gnokii --identify 2>&1 | more

The last few lines just keep repeating infinitely and nothing ever  
happens.

What am I doing wrong?

TIA,
