2.9 SLEEP MODES
There are two kinds of sleep modes, the “off mode” and “stand-by” mode as
described below:
2.9.1 Off mode
When the module is in the off mode it cannot receive any calls or receive any
AT commands but can be awakened by using PWON signal.
2.9.2 Stand-by Mode Management
There are three stand-by mode management controls:
 AT+KSLEEP=0
In this mode the sleep state is controlled by the host DTR and by the
firmware:
- DTR = 1 - The module never enters into the sleep mode
- DTR = 0 - The module enters the sleep mode when it is ready
and cannot be awakened with an AT command. To wake up the
module the user must toggle DTR to 1.
Remarks: Even in this mode it is possible to use DTR signals to go from
the data mode to the command mode. However, in this case, DTR has

 AT+KSLEEP=1
In this mode the sleep mode state is only controlled by the firmware.
The module enters the sleep mode when it is ready. The module may be
