Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H)
Send Voice Tone(s)
This command causes the modem to send DTMF digit or hookflash tones with the
duration specified by +VTD, to send DTMF digit or hookflash tone duration specified
by this command, or to send single or dual tone frequencies with duration specified
with this command.
AT+VTS=<string>
<string> The tone generation string consists of elements in a list where each
OK if the PC accepts the command.
ERROR if the modem encountered an error in parsing the subparameter or if the
selected frequency is out of range.
Using the +VTS command for tone generation without using any null elements:
AT=VTS=1,2,[1000,1300,50],{*6},{800,1300,50},9
The above string will perform as follows:
1. Play DTMF 1 with a duration given by the +VTD command.
2. Play DTMF 2 with a duration given by the +VTD command.
3. Play tone pair at 1000 Hz and 1300 Hz with a duration of 500 ms.
4. Play DTMF * with a duration of 60 ms.
5. Play tone pair at 800 Hz and 1300 Hz with a duration of 500 ms.
6. Play DTMF 9 with a duration given by the +VTD command.
+VTS=?
form <freq1>,<freq2>,<dur> , where <freq1> is the first frequency range,<freq2> is
the second frequency range, and<dur> is the duration range for the square brackets
and curly braces constructs. The units are in 0.01 seconds. The range of valid <dur>
values is that of the +VTD command.
Example: In the lines below, the modem responds to the +VTS=? command by
reporting that it supports two frequencies, both in the range of 200-3300 Hz, and
supports a duration range from 0 to 5 seconds.
AT+VTS=?
(200-3300), (200-3300), (0-500)
OK
Missing parameters are assumed to be the default value. Unspecified
values always default to 0 for frequencies, DTMF * for DTMF tones, and
+VTD for duration. The omission of commas (and associated
subparameters) is valid.

A single character which the modem interprets as a DTMF digit (0–9,
#, *, and A–D) or hookflash (!), with a duration given by the +VTD
command.
A 3-element string enclosed in square brackets "[freq1,freq2,dur]",
which the modem interprets as a general dual tone and duration
(dur) selection.
A 2-element string enclosed in curly braces "{X,dur}", which the
modem interprets as a DTMF digit ((0–9, #, *, and A–D) or hookflash
(!), with a duration (dur) different than that given by the +VTD
command.
