Line 16: * '''AT&D''' or '''AT&D0''' - Ignore DTR signal. A call will continue regardless of the DTR line, and the only way to end the call is with the escape sequence, or if it gets terminated by the other side. This setting is only used if the computer equipment cannot provide or control DTR. * '''AT&D1''' - Dropping the DTR signal puts the modem into Command Mode, ''without'' disconnecting the call. The computer may disconnect the call with the ATH command, or return to the call with ATO. This mode is useful if the computer wishes to change settings on the modem during the call (such as activating test modes). * '''AT&D2''' ''(default on most modems)'' - Dropping the DTR signal will cause a disconnect. Following the disconnect, ~~and~~the amodem ~~return~~returns to command mode. * '''AT&D3''' (not supported by all modems) - Dropping the DTR signal will cause a disconnect, followed by a reset (similar to ATZ).
