Table 3-4. Data Mode Command Descriptions (Continued)

Dial Command: This command causes the modem to immediately go off- hook as an originating modem and dial a telephone number with correspond- ing dial modifiers. Dial modifiers are parameters that define how the modem should dial the telephone number.

	Dial Modifiers
	0–9	Dialing Digits
	A, B, C,	Tone Dial Characters
	D, *, #
	P	Pulse Dial—configures the modem to use pulse dialing to
		dial a telephone number.
	R	Reverse Originate Mode—places the modem in answer
		mode. This modifier should be the last character in the dial-
		ing string (for example, ATDT 12345678R). After dialing the
		telephone number, the modem goes into data modem an-
		swer mode instead of originate mode.
	S = n	Dial NVRAM Telephone Number—causes the modem to dial
		a telephone number previously stored in the NVRAM with
		the AT&Zn=x command.
	T	Tone Dial—configures the modem to use DTMF tones to dial
D	none	a telephone number.
	W	Wait for Dial Tone—causes the modem to look for dial tone
		for a specified amount of time. If dial tone or the amount of
		time specified by the S-register, S6, times out, the modem
		processes the next command in the dial string. If a busy sig-
		nal is detected, the modem responds to the DTE with a busy
		response code and then goes into off-line command mode.
	,	Pause—causes the modem to pause or delay implementing
		the next parameter in the dial string by the time specified in
		S-register S8.
	!	Flash Hook—causes the modem to go on-hook for 0.75 sec-
		onds.
	@	Wait for Quiet Answer—causes the modem to wait for spec-
		ified amount of time (S-register S7) followed by 5 seconds of
		silence before processing the next dial modifier.
	;	Return to Idle State—causes the modem to enter online
		command mode without initiating a data modem handshake
		(used for phone directory auto-dialers).

<space> - ( ) Ignored by Modem—these four characters are ignored by the modem. Spaces also may be included in the dial string

	to separate area codes and numbers.
