18 COMMAND STRING - INTRODUCTION
“Command String” is a set of programmable scripts originally for Maestro Heritage modem. And now it is incorporated to
M100 2G. User can input sets of Command Strings to control various kinds of “Service”. Unlike AT command, Command
strings can be stored inside M100 2G and can be executed upon output of certain services.
18.1 Command String and “Service” Concept
“Command String” and “Service” operation mechanism
1. Use AT command to enter preset Command Strings
2. Command strings can be executed upon power up or directly by AT
commands
3. Executed Command Strings will drive some Services to be done (e.g.
sending SMS or setting output pins)
4. Executed Command Strings can also configure and control some
Services that have “trigger” capability.
5. These Services, when a certain pre-defined condition is matched (e.g.
timer reach zero) can “trigger” a stored Command String.
6. Execute stored Command String to control Services again
