AT &C

Carrier control. This parameter defines the operation of pin 8 (DCD) of the RS 232C interface.

AT &C0 = Always on

AT &C1 = Fixed to this setting – Carrier goes high when on line. AT &C3 = Off in command mode – On when modem on line

For compatibility only. ie modem will respond with OK but not take any action.

AT &D

Data Terminal Ready options

This command controls the handling of the DTR line. (Pin 20).

AT&D0 - DTR state is ignored and no action is taken. This is the equivalent of holding DTR permanently active (high).

AT&D1 - Returns the modem to command mode on loss of DTR. This is the same as issuing the +++ escape sequence, i.e. the modem will go into command mode, but will not drop the line.

AT&D2 - Prevents the modem from originating or answering a call unless DTR is raised by the DTE, and if the modem is online when DTR drops, the call will be disconnected.

AT &F

Restore Factory Configuration

Configures the modem to factory default settings (Does not default AT+ autosave commands).

AT&V

This command shows the general set up of the modem. Displays, for example (Version 3.03 firmware):
