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

AT	Parameter &
Command	Option	Description
	Con Msg	Connect Message
AT*CM0	=DTE Rate	Selecting DTE Rate results in the current DTE rate being displayed on your terminal after the
		connect message.
AT*CM1	=DCE Rate	Selecting DCE Rate results in the current DCE rate being displayed on your terminal after the
		connect message.
AT*CN1 –	Enter Phone #	See the AT&Z command description.
9,(phone no.)	=1–9
AT*CT0/	CTS=High	CTS is always high. Use this setting if you plan to use RTS/CTS or DTR/CTS Flow control.
AT&R1
AT*CT1	=Normal	The modem controls CTS as in normal handshaking. In V.25bis ACU operation, CTS follows
		DTR in command state; CTS is off in training/retraining and follows RTS in data mode.
		For AT ACU operation, CTS follows RTS in command state; CTS is off in training/retraining
		and follows RTS in data mode. If an ACU is not selected, CTS is low.
AT*CT2	=ACU On	CTS is on in ACU mode, goes off during training/retraining, and follows RTS in data mode.
AT*CT3/	=AsyncSync	CTS is on in asynchronous mode, and off in synchronous, ACU mode. In synchronous data
AT&R0		transfer mode, CTS is off in training/retraining and follows RTS in data mode. When CTS
		follows RTS in data mode, the setting of the RTS/CTS Delay option applies (if Mode=Direct).
AT*CT4	=RTS	CTS follows RTS. Use this setting if your application requires that CTS immediately follow
		RTS. If one of these flow control methods is used: Flow=RTS/CTS or Flow=DTR/CTS, then
		CTS does not follow RTS in a flow-off condition. When CTS=RTS, the RTS/CTS Delay
		(AT*DL) option is not available.
	Default Dial	Default Dialing
AT*DA0	=Off	The default dial feature is disabled.
AT*DA1 – 9	=1 – 9	The modem direct dials the telephone number stored in the memory address selected (memory
		addresses 1 – 9) when one of the following conditions occurs:
		•DTR=108.1 or Tail, and the DTE turns the DTR signal from off to on.
		•DTR=108.2, Esc, Discon, Reset, or High; the DTR signal is on; and either the front panel
		Talk/Data key ( at the Home position) is pressed, or control of the dial is switched to
		the modem with an exclusion key telephone.
		•ACU Select=AT, AT Form=DTR Dial, and the DTR signal transitions from off to on.
		This option also determines the telephone number dialed during restoral.
	Delay	Buffer Delay
AT*DB0	=Off	The Off setting disables the Delay option.
AT*DB1	=Buf or S38	This setting starts the buffer delay timer immediately upon detection of the disconnect request.
		When the timer is operating, the modem continues to process either the transmit or receive
		buffers. The modem disconnects when the buffers are empty or the timer expires, whichever
		occurs first. NOTE: When the modem is set for Direct mode, no data buffering occurs and the
		disconnect is immediate.
AT*DB2	=Buf & S38	This setting prevents the timer from starting until either the transmit or receive buffers have
		emptied. The modem then disconnects. Once the timer expires, when the modem is set to
		Direct mode, data is not buffered and the timer starts immediately.
