Motorola V.3600 Wait for Second Dial Tone W, Hook Flash, Switching to Answer Mode after Dialing R

AT Commands

Wait for Second Dial Tone — W

To wait for second dial tone insert a W in the dialing sequence.

AT D 9 W 323-8000

Instead of using a comma pause for an outside line, wait up to 30 seconds (time specified by S7) for a second dial tone.

Hook Flash — !

To flash the switchboard, insert an exclamation mark in the dialing sequence.

AT D T 9W 323-8000 ,!, #7 377

This inserts a 0.5 second on hook condition, usually for transferring a call or similar use.

In this example, the modem tone dials a 9, waits for the second dial tone, dials the phone number, pauses, flashes to start the transfer, pauses a second time, then uses #7 to transfer the call to extension 377.

Switching to Answer Mode after Dialing — R

To switch to answer mode after dialing, use an R at the end of the dial sequence.

AT D 554-2345 R

Use this command suffix to call an originate-only modem.

Remaining in Command Mode — ;

To remain in command mode after dialing, place a semicolon at the end of the dial sequence.

AT D 234-5678;

The modem will dial the telephone number entered but will not attempt to train when the remote service answers the call.

This is used to retain control so that further dialing tones may be entered with the following:

AT DTn;

where n= additional tones to be sent.
