Sorry for using not the right tool. Here is the trace from USBPcap.

The AT-commands are nice decoded. But the network-part is only for 
professionals  with built  automagic hex-translation in the eyes :-)

My intentioned traffic was "ping heise.de", the other things you see must be 
from windows and vpn stuff, despite I did not start the vpn explicitly, the 
background-service of cisco seems to check the network without being asked.

To remember my problem: I think the modemmanager does everything right. But 
wwan0 doesn't work. May be you can see what is difference between 
windows/linux.

Thomas
