Modem Initialisation Sequence
The modem attempts to communicate to the module
If the Modem and module communicate successfully:
In case of communication failure between the modem and module, the modem is automatically reset,
and initialisation is attempted once more:
In the case of a module that is unable to communicate with the modem, the display continuously
cycles between 'Modem Reset' and 'Modem Initialising' as the module resets the modem and
attempts to communicate with it again, this continues until correct communication is established with
the modem. In this instance, check connections and verify the modem operation.
