Chapter 2 – Configuration Commands
Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371B) 25
2.10 AT^SMSO Switch off Mobile Station
Description: AT^SMSO initiates the power-off procedure. High level of the module’s PWR_IND and
the URC “^SHUTDOWN” notifies that the procedure has completed and the module has
entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating
voltage until PWR_IND is High or until the URC “^SHUTDOWN” is displayed. Otherwise,
you run the risk of losing data. For further details on how to turn off the module see the [2].
Exec Command Syntax: ^SMSO
Response(s): ^SMSO: MS OFF, OK
Test Command Syntax: AT^SMSO=?
Response: OK
Unsolicited Result Code:
^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off in less than 1 second.
Notes:
• Do not send any other AT command after AT^SMSO.
• If AT^SMSO is entered on one of the Multiplexer channels, the ME closes the Multiplexer channels, terminates
the Multiplexer, and deactivates all other functions. Then the URC “^SHUTDOWN” will be issued on the
physical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with
the Multiplexer driver.
2.11 AT+GCAP Request Complete TA Capabilities
List
Description: AT+GCAP returns a list of additional capabilities.
Exec Command Syntax: AT+GCAP
Response(s): +GCAP: <name>, OK
Test Command Syntax: AT+GCAP=?
Response: OK
Parameter Description:
<name>
e.g., +CGSM,+FCLASS
Note:
• +CGSM: The response text shows which GSM commands of the ETSI standard are supported.
2.12 AT+CMEE Mobile Equipment Error Message
Format
Description: AT+CMEE controls the format of the error result codes that indicates errors related to the
Multi-Tech wireless modem’s functionality. Format can be selected between plain
“ERROR” output, error numbers or verbose “+CME ERROR: <err>” and “+CMS ERROR:
<err>” messages.
Possible error result codes are listed in Table 2.6, General “CME ERROR” Codes (GSM
07.07), Table 2.5, GPRS related “CME ERROR” Codes (GSM 07.07) and Table 2.8, SMS
related “CMS ERROR” Codes (GSM 07.05).
In Multiplexer mode, the setting applies only to the logical channel where selected. The
setting on the other channels may differ.
