Re: communication freeze after send sms

hummm. you are using direct at command.
please if possible using

gammu -c gammurc -d textalldate -f gammu6.log identify

where gammurc is

[gammu]
device = /dev/ttyUSB2
connection = at9600

and gammu6.log will output (be sure use root user) see your device at dmesg
file.
see that there are some delay abount 7 seconds to gammu say that is not a
device there but we need display what is going on.
