Valid Dial Command Modifiers
Dial command modifiers are parameters entered in the dial command string which specify how, when, and
what number to dial. The following is a list of parameters the 391x Series modems recognize:
T — Tone (DTMF) dial. Any digit 0–9, *, or # can be dialed as tone.
P — Pulse dial. Only the digits 0–9 can be dialed in Pulse Dial mode.
NOTE: Once a dialing method (tone or pulse) has been specified, it will only remain active until the end of
that dial string. The modem defaults to the value set by the Dialer Type configuration option.
, — Pause. Causes the modem to pause before processing the next character in the dial string.
The length of this pause is determined by the setting of the Pause Time configuration option
(refer to the Line Dialer configuration option group) or by the value held in S-Register S8.
W — Wait for tone dial. The modem waits for a second dial tone before processing the dial string.
This can be the initial dial tone or can be used when dialing through a tandem PBX.
R — Reverse Dial mode. Causes the originating modem to send out an answertone once it no
longer detects ringback. (Ringback is the ring you hear at the originating site when making a
call.) The R modifier must be the last character in the dial string.
@ — Quiet answer. Wait for five seconds of silence after dialing the number. If the silence is not
detected, the modem sends the NO ANSWER result code to the DTE or displays the No
Quiet Answer LCD status message.
! — Hook flash. Causes the modem to go on-hook for 0.5 seconds then return to off-hook.
; — Return to Command mode. Causes the modem to return to Command mode after dialing a
number without disconnecting the call.
Space — Ignored by the dial string, can be included to enhance readability.
– — Ignored by the dial string, can be included to enhance readability.
( ) — Ignored by the dial string, can be included to enhance readability.
← — End of Number. Hides all characters appearing on the LCD entered to the right of this
indicator.
