Chapter 10 − Modem Mode AT Commands, S-Registers, and Result Codes
P Select pulse dialing: pulse dial the numbers that follow until a "T" is encountered.
Affects current and subsequent dialing. Some countries prevent changing dialing
modes after the first digit is dialed.
T Select tone dialing: tone dial the numbers that follow until a "P" is encountered.
Affects current and subsequent dialing. Some countries prevent changing dialing
modes after the first digit is dialed.
R This command will be accepted, but not acted on.
S=n Dial the number stored in the directory (n = 0 to 3). (See &Z.) (S=n is not
available with V.22bis).
! Flash: the modem will go on-hook for a time defined by the value of S29. Country
requirements may limit the time imposed.
W Wait for dial tone: the modem will wait for dial tone before dialing the digits
following "W". If dial tone is not detected within the time specified by S7 (US) or
S6 (W-class), the modem will abort the rest of the sequence, return on-hook, and
generate an error message.
@ Wait for silence: the modem will wait for at least 5 seconds of silence in the call
progress frequency band before continuing with the next dial string parameter. If
the modem does not detect these 5 seconds of silence before the expiration of
the call abort timer (S7), the modem will terminate the call attempt with a NO
ANSWER message. If busy detection is enabled, the modem may terminate the
call with the BUSY result code. If answer tone arrives during execution of this
parameter, the modem handshakes.
& Wait for credit card dialing tone before continuing with the dial string. If the tone
is not detected within the time specified by S7 (US models) or S6 (W-class
models), the modem will abort the rest of the sequence, return on-hook, and
generate an error message.
, Dial pause: the modem will pause for a time specified by S8 before dialing the
digits following ",".
; Return to command state. Added to the end of a dial string, this causes the
modem to return to the command state after it processes the portion of the dial
string preceding the ";". This allows the user to issue additional AT commands
while remaining off-hook. The additional AT commands may be placed in the
original command line following the ";" and/or may be entered on subsequent
command lines. The modem will enter call progress only after an additional dial
command is issued without the ";" terminator. Use "H" to abort the dial in
progress, and go back on-hook.
^ Toggles calling tone enable/disable: applicable to current dial attempt only.
( ) Ignored: may be used to format the dial string.
-
Ignored: may be used to format the dial string.
<space> Ignored: may be used to format the dial string.
<i> Invalid character: will be ignored.
> If enabled by country specific parameter, the modem will generate a grounding
pulse on the EARTH relay output.
Disables echo command.
Enables echo command.
The modem will release the line if the modem is currently online and will terminate any
test (AT&T) that is in progress. Country specific, modulation specific, and error
correction protocol specific (S38) processing is handled outside of the H0 command.
If on-hook, the modem will go off-hook and enter command mode. For US models, the
modem will remain off-hook. For global models, the modem will return on-hook after a
period of time determined by S7.
