Sorry, I do not understand, what do you mean in this point.

Connected modem is detected as a new serial port in linux (/dev/ttyUSB0) so
IMHO it is necessary to set the proper baud rate to establish communication.

I have solved the problem using following AT commands:

   - open the communication with the modem using the speed 460800
   - AT+IPR=115200[ENTER]
   - close connection
   - open the communication with the modem using the speed 115200
   - AT&W[ENTER]

the communication speed of the modem is set to the 115200 and the
configuration is stored to the Non-volatile Memory.

After that gammu (I am on 1.23.1 version) starts working with SIMCOM SIM600

Zařízení          : /dev/ttyUSB0
Výrobce             : SIMCOM_Ltd
Model                : unknown (SIMCOM_SIM600)
Firmware             : Revision:1604B06SIM600M64_INTEL
IMEI                 : 355735004112282
Nelze přistoupit na SIM kartu.
