Dial Modifiers

Modifier

Function

Description

W

Dial Wait

Instructs the modem to stop and wait for a dial tone. If the modem

w

 

does not detect a dial tone after a specified period, it aborts the

:

 

call. The factory default for dial wait is country-specific (refer to

 

Appendix C for details). In the U. S. A., the default is two seconds.

 

 

 

 

You can change this interval using the Dial Wait option.

 

 

 

K

Pause

When any of these modifiers are encountered in a dial string or

k

Delay

command line, the modem pauses. The factory default pause delay

<

 

is three seconds. This default can be extended with the Pause

 

Delay command. The comma modifier can be used as a command

,

 

 

outside the dial string.

 

 

 

 

 

P

Pulse

When either of these modifiers are encountered in a dial string, if

p

 

Dial=Auto (AT*PT—DIALING OPTS menu), the Dial setting is

 

 

not changed from Auto. If set to other than Auto, the pulse/tone

 

 

setting is modified to force pulse dialing.

 

 

If no pulse dial modifier is inserted in the number stream, the

 

 

modem dials according to the pulse/tone setting of the Dial option

 

 

in the front panel DIALING OPT’S menu. These modifiers can

 

 

also be used as commands outside the dial string.

 

 

 

T

Tone

When either of these modifiers are encountered in a dial string, if

t

 

Dial=Auto (AT*PT—DIALING OPTS menu), the Dial option

 

 

setting is not changed from Auto. If set to other than Auto, the

 

 

pulse/tone setting is modified to force tone dialing.

 

 

If no tone dial modifier is inserted in the number stream, the

 

 

modem dials according to the pulse/tone setting or the Dial option

 

 

in the front panel DIALING OPT’S menu. These modifiers can

 

 

also be used as a command outside of the dial string.

 

 

 

&

Flash

Instructs the modem to flash hook (a control signal used by many

!

 

PBXs to enable special dial features, such as transferring a call).

 

 

 

;

Return to

Instructs the modem to return to command state after dialing,

 

command

without breaking the connection. The modem can dial but cannot

 

state after

train, and no call progress messages are received. This modifier is

 

dialing

used when calling an electronic service that permits the user to

 

 

transmit numbers using tones, once a connection is established.
