of S29. Country requirements may limit the time imposed.
@ 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 will handshake.
$ Wait for credit card dialing tone before continuing with the dial
string. If the tone is not detected within the time specified by S7 or
S6, the modem will abort the rest of the sequence, return on-hook,
and generate an error message.
& Wait for credit card dialing tone before continuing with the dial
string. If the tone is not detected within the time specified by S7 or
S6, 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 commands while remaining off-hook. The
additional 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.
T - Set Tone Dial Default
This command forces DTMF dialing until the next P dial modifier or P command is received.
The modem will set an S-Parameter bit to indicate that all subsequent dialing should be
conducted in tone mode. Note that the DP command will override this command. Clears S14 bit 5.
This command may not be permitted in some countries. (See P.)
Syntax
T
Result Codes
OK
P - Set Pulse Dial Default
This command forces pulse dialing until the next T dial modifier or T command is received.
Sets S14 bit 5.
As soon as a dial command is executed which explicitly specifies the dialing mode for that
particular call (e.g., ATDT..), this command is overridden so that all future dialing will be
tone dialed. (See T command.)
This command may not be permitted in some countries.
A - Answer
The modem will go off-hook and will attempt to answer an incoming call if correct conditions
are met. Upon successful completion of answer handshake, the modem will go on-line in
answer mode. This command may be affected by the state of Line Current Sense, if enabled.
(Most countries do not require Line Current Sense.) Operation is also dependent upon
+FCLASS command and country-specific requirements.
