"Command String" and "Service" operation mechanism:
1. Use AT command to enter preset Command String.
2. Command strings can be executed upon power up or directly by AT commands.
3. Executed Command String will drive some Services to be done (e.g. sending SMS or setting output pins).
4. Executed Command String can also configure and control some Services that have "trigger" capability.
5. These Services, when a certain predefined condition is matched (e.g. timer reach zero) can "trigger" a stored
Command String.
6. Execute stored Command String to control Services again.
