Hi all

I have lenovo x200t with wwan module and I need to send and receive sms from laptop.
Actually I'm already did this successfully one time, but when I use wwan module for 3G Internet and after that I can't connect to wwan from wammu/gammu. I tried to reboot but it fails again with this errors

gammu sendsms TEXT pnone_number
Error opening device. Unknown, busy or no permissions.
On wammu I've got - timeout error.

My config
Device - /dev/ttyACM2
Connection - at
Model - at

As I said above I'm already did this with this setting and everything worked perfect.

Please help
