Because the comma (,) dial modifier is present, the modem delays before dialing the telephone number 5551212.! : Using the Hook Flash. The exclamation point (!) dial modifier causes the modem to go on-hook (hang up) for one-half second and is equivalent to holding down the switch-hook on your telephone for one-half second. This feature is useful when transferring calls.

W : Wait for a Subsequent Dial Tone. The W dial modifier causes a modem to wait for an additional dial tone before dialing the numbers that follow the W. The length of time the modem waits depends on the value in S- Register S7. The modem can be instructed to dial through Private Branch Exchanges (PBXs) or long-distance calling services that require delays during dialing. This can be done with the W command to wait for a secondary dial tone or with a comma (,) command to pause for a fixed time and then dial.A/ : -- Repeat. This command does not use the AT prefix nor does it require a carriage return to enter. Typing this command causes the modem to repeat the last command line entered, and is most useful for redialing telephone numbers that are busy.

&Fn : Factory Defaults. This command (in which n=0 or 1) returns all parameters to the selected set of factory defaults if the modem has factory defaults; not all modems do.

H : Hang Up. This command tells the modem to go "on-hook," or disconnect, the telephone line.

O : Online. This command returns the modem to the on-line mode and is usually used after the escape sequence (+++) to resume communication.

Zn : Reset Modem. This command (in which n=0 or 1) resets the modem to the configuration profile stored in non-volatile memory location 0 or 1.

Making a Call

The following examples show how to place a call using several of the dial modifiers.

ATD 1234567 The modem dials the telephone number 1234567 and then waits for a carrier from a distant, or remote, modem. If no carrier is detected within a given time (as defined by the initial settings in S-Register 6), the modem automatically releases the line and sends a NO CARRIER result code. If a carrier is detected, the modem gives a CONNECT result code and goes online, allowing communications with the remote modem. The connection between the two modems ends when any of the following occurs causing the modem to hang up, return to command mode, and send the NO CARRIER response:

• The local modem loses the carrier signal from the remote modem.
• The Hang Up command (H) is sent.
• The DTR interface signal is dropped between the local DTE and modem when the &D2 or &D3 command is in effect.

NOTE: All ampersand (&) based commands are totally dependent on implementation. They are extensions from the original HAYES command set. AT &F1DT9,P5551234 [Enter]

Manually Dialing with the Telephone

To manually dial the phone, you should be in your communications software's command mode.

1. Lift the receiver of the telephone and dial the number you wish to call.
2. ??????:ATH1and press ENTER to connect the modem and then hang up the receiver.
3. ??????:AT0and press ENTER to tell the modem to go online.

Manual Answer

When the automatic answer feature (S-Register S1) is not being used, incoming calls can be answered manually by typing ATA and then pressing ENTER when an incoming call is received. The modem will answer the incoming call and enter the on-line mode.
