A/	Repeat Last Command. Reexecutes last command string. (Not to be		Call Setup\
	preceded with AT or followed by pressing the Return key.)		Answer
A	Answer Mode. Goes off-hook and attempts to establish a connection		None
	without waiting for a ring.
Dn	Dial. Begins the dialing sequence. The dial string n (modifiers and		None
	telephone number) is entered after the D command.
	Any digit 0–9, *, or # may be dialed as a DTMF tone. Only the digits 0–9
	can be dialed in Pulse Dial mode. The following example shows how to
	dial through a PBX. The dial string consists of the command string and
	the telephone number:
		ATD9W5551234
	Modifiers include the following parameters:
	T
		— Tone (DTMF) dial. Any digit 0–9, *, or # can be dialed as
		tone.
	P
		— Pulse dial. Only digits 0–9 can be dialed in Pulse Dial
		mode.

NOTE: Once a dialing method (tone or pulse) has been specified, it will only remain active until the end of that dial string. The modem defaults to the value set by the Dialer Type configuration option.

,— Pause. Causes the modem to pause before processing the next character in the dial string. The length of this pause is determined by the setting of the Pause Time configuration option (refer to the Line Dialer configuration option group) or by value held in S-Register S8.

W— Wait for dial tone. The modem waits for a second dial tone before processing the dial string. This can be the initial dial tone or can be used when dialing through a tandem PBX.

For example, 9W 555-6789.

R— Reverse Dial mode. Causes the originating modem to send out an answertone once it no longer detects ringback. (Ringback is the ring you hear at the originating site when making a call.) The R parameter must be the last character in the dial string. For correct operation, at least one ringback must be detected; therefore, the remote modem should be configured to answer on the second ring or subsequent rings.
