AT+C commands for GSM

Special AT commands are used for controlling GSM-related functions of the GSM
Module M1 such as PIN entry, network selection and IMEI output and for controlling the
short message service. These commands start with AT+C and are specified in the Tech-
nical Specifications (TS) GSM 07 .07 for the general part and GSM 07 .05 for SMS from the
ETSI (European Telecommunications Standards Institute). Standardization is not yet com-
plete. Some of the commands implemented in the GSM Module M1 may still be
changed within the framework of the standardization process. For the purpose of future
compatibility, these commands are always prefixed by +CXX.
Example:
Enter:
GSM module
The implementation of the AT+C commands for GSM-related functions of the GSM
Module M1 is based on TS GSM 07 .07 Version 0.1.0.
