For applications or situations where hardware control of the DTR signal is not possible, the
modem can be configured to ignore DTR. When Ignore DTR is enabled, the modem operates
as if the DTR signal is always asserted.
n=0 : Use hardware DTR. (default).
n=1 : Ignore DTR.
n=3 : Ignore DTR and assert DSR. This value is deprecated, and it is recommended to use &S to control
the DSR instead. When this value is set to 3, &S will automatically be set to 0. See also: &D and &S.
Command Response Mode.
n=0 : Terse (numeric) command responses
n=1 : Verbose command responses (Default).
