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. At that time, it wonʹt 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 start‐up mode as it is configured for the modem.
