I have installed gammu, gammu-smsd and libgammu-i18n to debian 8.4.
I configured to use it ttyUSB0 and at115200, model auto. When I run gammu-detect it will find Phone on USB serial port Prlific_Technology_Inc. USB-Serial_Controller, coection at
Device is Siemens MC35i
but when I run gammu identify it says No response in specific timeout. Probably phone not coected.
What I can do to debug this ? I had to do sudo chmod 777 /dev/ttyUSB0 to change permissions because without above I get only Error opening device, you don't have permissions.
