Power Effect on Modem State
Once the transition from powered on to standby, low-power mode starts, the modem will change
state to AT mode. This results in the current mode being gracefully terminated. For the brief period
when the modem is preparing for low-power mode, the modem will remain in AT mode (i.e. won't
auto-answer, ATD will fail, etc.). Once low-power mode is entered, the modem will then discard
any data received on the host port.
When the modem is woken from low-power mode, the same behavior occurs as upon power on.
The modem starts in AT mode, and then after 5 seconds will enter the default mode (See “Host
Modes” on page
20).
