gnokii --> Initialization failed (11)

[Felix Hammer]

Hello 

I tried to use the NOKIA 3220. it should be working like 6510
this is my config-file:
----------------------------------------------
port = /dev/tts/USB0
model = AT
initlength = default
connection = serial
use_locking = no
serial_baudrate = 19200
[connect_script]
TELEPHONE = 12345678
[disconnect_script]
[logging]
debug = on
rlpdebug = on
xdebug = off
--------------------------------------------

i use a serial/USB connection. the cable is called GS-AC101!
i use GNOKII Version 0.6.4 from the tarball

when i try gnokii --identify i get always:
----------------------------------------------
gnokii --identify
