Command Reference
Rev 3.2 Oct.05 99
+IPR (continued)
Fixed local data rate (continued)
Note: Watcher can only communicate with the modem when the data rate is at
115200 kbps. If you intend to run Watcher, using autobaud or any setting other
than 115200, is NOT recommended.
Note: When using autobauding, issuing a “ping”
AT<CR>
command (with no
other characters) should yield an
OK
response. If not, send another
AT<CR>
to
permit the modem to adapt to the host data rate.
Note: When you change the data rate using +IPR, you must issue AT&W (to
preserve the setting) then power cycle the modem.
+IPR?
returns the current setting.
+VTD=<n>
+VTD?
Tone duration
Defines the length of tones emitted when using the
+VTS
command (page 99),
with
<n>
in tenths of a second between 1 and 255. It does not affect the
D
command.
If
<n>=0
the value is set to the default. (See “Factory Default Settings” on
page 107.)
+VTD?
returns the current setting.
+VTS=<DTMF>
or
+VTS=<tone1>,
<tone2>,
<duration>
or
+VTS=<DTMF>,
<duration>
DTMF tone generation
This command allows the transmission of DTMF (Dual Tone Multi-Frequency,
also known as Touch-Tone™ tones, used to access voice mail and other tone-
controlled remote systems. The command is separate from
D
, which is used
only for dialing.
The command is write-only, and does not operate in data modes of operation.
Supported values
The string parameter of the command consists of combinations of the following,
separated by commas:
1.
+VTS=<DTMF>
is a single ASCII character in the set
0–9, #,*,A–D
. This is
interpreted as a single ACSII character whose duration is set by the
+VTD
command (page 99). In GSM, this command type operates only in voice
mode.
2.
+VTS=<DTMF>,<duration>
is interpreted as a DTMF tone of different
duration from that mandated by the
+VTD
command (page 99). In GSM,
this operates only in voice mode.
