Triggering the RESET# signal will lead to loss of all data in the modem and removal of system drivers. It
will also disconnect the modem from the network.
The module can be reset by pulling down the RESET# pin for 250
–600 ms. An open collector/drain driver
or a button can be used to control the RESET# pin.
