Parameters and Values
<opmode> Operating mode.
0 Normal operating mode. The module exits the alarm mode, enters the normal
operating mode. Alarm activity—for example alarm tone playing—is stopped and
an OK result code is returned.
Notes
The alarm mode is indicated by status ON of hardware pin CTS and by status ON of pin DSR. The power
saving status is indicated by a CTS - OFF and DSR - OFF status. The normal operating status is indicated by
DSR - ON.
During the alarm mode the device will not scan the network or register to any network. Therefore, the
device cannot dial or receive any call or SM. The only commands that can be issued to the module in this
state are #WAKE and #SHDN. Every other command must not be issued during this state.
