Configuring automatic reboot
A 3G modem might be halted in an unstable 3G network or when application environment changes,
and cannot automatically dial to access the network. Automatic reboot minimizes the need to manually
reboot a 3G modem.
With automatic reboot enabled, a 3G modem automatically reboots when it consecutively fails to deploy
a configuration directive or when consecutive response timeouts occur. To avoid repeated automatic
reboot resulting from dialup failures due to configuration errors, the 3G modem automatically reboots
only after at least one dialup succeeded since the last reboot.
