Dn – Dial
This command directs the modem to go on-line, dial according to the string entered and attempt to
establish a connection. If no dial string is supplied, the modem will go on-line and attempt the
handshake in originate mode.
Dial Modifiers.
The valid dial string parameters are described below.
0-9 DTMF digits 0 to 9.
* The 'star' digit (tone dialling only).
# The 'gate' digit (tone dialling only).
A-D DTMF digits A, B, C, and D. Some countries may prohibit sending of these digits
during dialling.
J Perform MNP 10 link negotiation at the highest supported speed (for this call only).
(also refer to AT*H)
K Enable power level adjustment during MNP 10 link negotiation (for this call only).
(also refer to ATMn)
L Re-dial last number: the modem will re-dial the last valid telephone number. The L
must be immediately after the D with all the following characters ignored.
P Select pulse dialling. In most countries is this not available
T Select tone dialling (DTMF) tone dialling is normally used in this modem.
S=n Dial the number stored in the directory (n = 0 to 3 or 0 to 19 depending on the modem
model). (See &Z.)
W Wait for dial tone: the modem will wait for dial tone before dialling the digits
following ”W”. If dial tone is not detected within the time specified by S6 the modem
will abort the rest of the sequence, return on-hook, and generate an error message.
, Dial pause: the modem will pause for a time specified by S8 before dialling the digits
following ”,”.
; Return to command state. Added to the end of a dial string, this causes the modem to
return to the command state after it processes the portion of the dial string preceding
the ”;”. This allows the user to issue additional AT commands while remaining off-
hook. The additional AT commands may be placed in the original command line
following the ”;” and/or may be entered on subsequent command lines. The modem
will enter call progress only after an additional dial command is issued without the ”;”
terminator. Use ”H” to abort the dial in progress, and go back on-hook.
^ Toggles calling tone enable/disable: applicable to current dial attempt only.
(-),<space> Ignored: may be used to format the dial string.
If the ATD.. command returns ERROR the ATX0 is probably set in a country that does not allow
blind dialling.
