Dial Modifiers
Dial modifiers perform special functions within a dial
command. For example,
instructs the modem to use tone dialing (T), to access a
number outside a PBX (9), to wait for dial tone (W), to
dial the number 1552368, to do a hook-flash (i.e. timed

Function
Dialing digits and characters. The digits and characters 0-9 A B C D # * specify what numbers the
modem dials. The characters A B C D # * work only when tone dialing is used, they are ignored when
pulse dialing is used. The characters A, B, C, and D may be disabled in countries prohibiting their use.
Pulse dialing. P selects the pulse method of dialing. P can be issued within a dial command or as a
separate command. The default method of dialing is Pulse.
Originate a Call in Answer Mode. R makes the modem handshake in answer mode so it can originate
a call to an originate-only modem.
Tone dialing. T selects the tone method of dialing. T can be issued within a dial command or as a sep-
arate command. The default method of dialing is Pulse.
Wait for dial tone. W makes the modem wait for a dial tone before proceeding. If no dial tone is detect-
ed the modem hangs up the telephone line and returns the NO DIALTONE result code.
Delay Processing of Next Character. A comma (,) makes the modem pause for the length of time in S-
register S8 before processing the next character in a dial string.
Wait for Quiet Answer. @ makes the modem listen for 5 seconds of silence before continuing. The
modem will wait up to the length of time in S-register S7. If 5 seconds (configurable by country) of
silence are not detected within the time period in S-register S7, the modem hangs up and returns the
NO ANSWER result code. If 5 seconds of silence are detected, the modem continues processing the
other characters in the dial string.
Timed Break Recall (Hookflash). A ! makes the modem hang up the telephone line for the length of
time in S-register S29, then take the telephone line off hook again. This is frequently used to access a
PBX’s call transfer function.
Return to Command State after dialing. A semicolon (;) tells the modem to return to command state
after dialing without breaking the telephone line connection and without handshaking with the other
modem. The semicolon may only be used when calling a voice mail system that permits tones to trans-
mit numbers once a connection has been established.
