AT Command Reference (continued)

 

DnDial

This command instructs the modem to begin the dialing sequence. The dial string (n, including modifiers and the telephone number) is entered after the ATD command.

A dial string can be up to 60 characters long. Any digit or symbol (0¾9, *, #, A, B, C, D) may be dialed as touch- tone digits. Characters such as spaces, hyphens, and parentheses do not count¾they are ignored by the modem and may be included in the dial string to enhance readability.

The following may be used as dial string modifiers:

LRedials last number. Should be the first character following ATD, ignored otherwise.

P Pulse dialing.

T Touch-tone dialing (default).

, Pause during dialing. Pause for time specified in Register S8 before processing the next

character

in the dial string.

W Wait for dial tone. Modem waits for a second dial tone before processing the dial string.

V The modem switches to speakerphone mode and dials the number. An ATH command may be

used to

disconnect the voice call.

@Wait for quiet answer. Wait for five seconds of silence after dialing the number. If silence is not

detected, the modem sends a NO ANSWER result code back to the user.

!Hook flash. Causes the modem to go on-hook for 0.5 seconds and then return to off-hook.

;Return to command mode. Causes the modem to return to command mode after dialing the

number,

without disconnecting the call.

^ Disable data calling tone transmission.

S=n Dial a telephone number previously stored using the &Zn=x command (see the &Zn=x command for

 

further information). The range of n is 0—3.
