[n init string] — Event Based Command
Parameters | n = 0 or 1 |
| init string = any valid AT command(s) except |
| Z (reset) |
Defaults | n = 0 |
| init string = NULL |
The event based command is unique in that it allows single or multiple AT commands to be associated with an event identified by an event identifier “n”. Currently only two events are identified; event 0 indicates that the modem is currently operating using a land line based communication line; event 1 indicates that the modem is currently operating using a cellular based communications line. These events can change dynamically, and thus whenever a change is detected the modem will execute the AT commands associated with the event automatically.
Multiple event based commands can be on the same command line or can be entered on separate command lines. The AT command(s) associated with an event are stored in volatile memory, powering off the modem or executing the ATZ command will clear the command(s). A NULL init string will also serve as a way of clearing command(s) associated with an event.
All commands between the [n and then next], or [n, or the end of the command line will be associated with the event n. All commands will be verified and commands that require interaction or return information should not be used since these will be executed based on changing events.
Examples
AT[0&F&C1&D2&S1W1S95=18]
The above command stores the &F&C1&D2&S1W1S95=18 commands for event 0 (land based connection) and will be automatically executed when a change of event from cellular back to land based is detected.
AT&F&C1&D2&S1[0S95=18][1S95=44)M1*H2:E0]
