Chapter 1 – AT Commands, S-Registers, and Result Codes
D
Description:
Dial
This command instructs the modem to begin the dialing sequence. The dial string,
which is made up of the telephone number and dial modifiers is entered after the D
command.
A dial string can be up to 60 characters long. Any digit or symbol may be dialed as
touchtone digits. Characters such as spaces, hyphens, and parentheses are ignored
by the modem and may be included in the dial string to enhance readability.
Syntax: ATD<dial_strings>
Dial String Values: Phone number and dial modifiers.
Dial string modifiers:
L
P
T
V
W
,
;
!
@
^
$
Redial the last number. (Must be placed immediately after ATD .)
Select pulse-dialing.
Select tone-dialing.
Dial using speakerphone. Instructs the modem to switch to speakerphone
mode and dial the number. Use the ATH command to disconnect the voice
call.
Wait for dial tone. This command instructs the modem to wait for a second
dial tone before processing the dial string. ( X2 , X4 , X5 , X6 , or X7 must be
selected.)
Pause during dialing for the amount of time set in register S8.
Return to command mode. Instructs the modem to return to command mode
after it has finished dialing without disconnecting the call. This modifier must
be the last character in the dial string.
Hook flash. Instructs the modem to go on-hook for 0.5 seconds and then
return to off-hook.
Wait for quiet answer. Instructs the modem to wait for 5 seconds of silence
after dialing the number. If silence is not detected, the modem sends a NO
ANSWER result code back to the user.
Disable data calling tone transmission.
Detect AT&T call card “bong” tone. The character should follow the phone
number and precede the user’s call card number:
ATDT1028806127853500$123456789
S=<location> Dial a number previously stored in the register. Instructs the modem
to dial a telephone number previously stored using the
&Z<location>=<dial_string> command. Valid storage locations are 0 to 2
(0–1 for Parallel {internal}).
Example: ATDS=2
Default:
Result Codes:
T
CONNECT if a connection is established and the extended result code
parameter is equal to 0. (See X<value> – Select Result Code and
Monitor Call Progress).
CONNECT <rate> if a connection is established and the extended result code
parameter is not equal to 0.
NO CARRIER if a connection cannot be established or the modem aborts the
connection on request of the host system.
BUSY if the W or @ modifiers are used and a busy signal is detected.
NO ANSWER if the @ modifiers is used and the remote ring followed by 5
seconds of silence is not detected before expiration of the connection
timer. See S7 – Connection Completion Time-Out.
OK if the commands are aborted or DTR is turned off by the host system when
the data terminal ready control is not set to 0. See &D<value> – Data
Terminal Ready (DTR) Control.
ERROR if the modem is in on-line command mode when receiving the A
command.
