6.4.1Description
Controls the automatic answering feature of the DCE. If set to 0, the automatic answering is disabled,
otherwise it causes the DCE to answer when the incoming call indication (RING) has occurred the number of
times indicated by the value.
For an incoming CSD call, if the autoanswering is enabled and the <value> parameter of &D command is
set to 2, the autoanswering only works if the DTR line of the AT interface with activated autoanswering
is set to ON. Otherwise, if DTR is OFF, then the call is rejected. If the <value> parameter of &D command
is not set to 2, the DTR state has no impact on autoanswering.
