AT Commands, Cross-Referenced to Front Panel Options (Continued)

AT	Parameter &
Command	Option	Description
AT*AS1	=Always	A dial call is always answered. As soon as the dial call is answered, the leased line connection
		is dropped (with auto-answering, the leased line is dropped after the correct number of rings).
		If training on the dial line fails, the modem returns to the leased line.
	Auto Type	Auto Type
AT*AY0	=CCITT	During answer-back tone, the modem attempts to negotiate a connection in the V.32
		modulation mode. As soon as answer-back tone ends, if a V.32 tone has not been detected
		during ABT, the modem attempts to negotiate a connection in the V.22bis modulation mode.
AT*AY1	=Codex	During answer-back tone, the modem attempts to negotiate a connection in the V.32
		modulation mode. After sending answer-back tone, the modem continues to attempt to
		negotiate a connection in the V.32 modulation mode. If unsuccessful, the modem tries to
		negotiate a connection in the V.22bis modulation mode.
	Blind Dial	Blind Dial
		Determines the time the modem waits before dialing; once time has expired, the modem dials
		without waiting for a dial tone.
AT*BD0	=2	The modem waits 2 seconds before dialing.
AT*BD1	=4	The modem waits 4 seconds before dialing.
AT*BD2	=S6	The modem waits the amount of time specified by S-Register 6 before dialing.
	Break	Break Handling
		Controls how the modem handles the break signal in reliable and auto-reliable data modes.
		Break signals are sent to the DTE for the duration specified in S-Register 97.
AT*BK0	=Destruct	The modem uses destructive and expedited break handling. It passes the break to the remote
		site immediately and deletes all data from its buffers. NOTE: Destructive breaks reinitialize
		data compression tables for MNP-5 and V.42bis.
AT*BK1	=Expedited	The modem uses nondestructive and expedited break handling. It passes the break to the
		remote site immediately without deleting data from its buffers.
AT*BK2	=Standard	The modem uses standard break handling. It passes the break to the remote site in sequence
		with any transmit data from its buffers.
	Mode	Answer/Originate Mode
AT*CA0	=Orig	The modem operates as an originating modem in a manual answer/dial application.
AT*CA1	=Answer	The modem operates as an answer modem in a manual answer/dial application.
AT*CA2	=External	The signal from the DTE on EIA/TIA 232-D Pin 11 determines whether the modem is in
		answer or originate mode. If the signal is off, the modem is in originate mode; if the signal is
		on, the modem is in answer mode
AT*CA3	=Auto A in O	The modem configures itself as an originating modem after auto-answering a call. In leased-
		line operation, the modem functions as if it is set to originate calls. NOTE: The functions
		provided by this setting only apply when the modem auto-answers.
	DCD Loss Dis	DCD Loss Disconnect
AT*CD0	=Off	The modem will not disconnect due to loss of carrier.
AT*CD1	=3 s	The modem hangs up if it loses carrier for 3 seconds.
AT*CD2	=7 s	The modem hangs up if it loses carrier for 7 seconds.
AT*CD3	=S10	The modem checks the value stored in S-Register 10 to determine when it disconnects due to
		loss of carrier. See the “S-Registers” section in Chapter 5 for more information.
