This must be the last command on a command line. ATD causes the modem to go off-hook, dial according to the parameters entered, and attempt to establish a connection. If there are no parameters, then the modem goes off-hook in originate mode without dialling the number.

Punctuation may be used for clarity. Parentheses, hyphens and spaces are ignored. If an invalid character is entered, that character and all subsequent characters in the dial string are ignored. The modem truncates dial strings to 40 characters.

The ATD Parameters are:

L Dials the last dial string that was dialled.

PUse Pulse Dialling. Placed at the end of the command string and before the dial string. Causes the modem to pulse dial the numbers.

TUse DTMF Dialling. Placed at the end of the command string and before the dial string. Causes the modem to use DTMF tones to dial.

RReverse Mode. Allows the modem to call an originate-only modem by forcing the call into answer mode. Must be entered as the last character of the command string (just before the [ENTER]).

&Wait for calling card bong. If bong is not detected within the time specified by S7 (default = 30 seconds), the modem disconnects and returns an error message.

!Hookswitch flash. Causes the modem to go on-hook for 700 milliseconds and then off-hook.
