+VTD = n
DTMF / Tone Duration Timer
.
This command sets the default DTMF / tone generation duration in
10 ms units for the +VTS command.
Default time is 1 second
(n = 100).
+VTS = [<freq1>,
<freq2>, <dur>]
DTMF and Tone Generation.
This command can be used to produce DTMF tones, single-frequency
tones, and double-frequency tones. Note that the bracket characters are
required for correct operation.
<freq1>
Frequency one, which has a range of 0, 200-3200 Hz.
<freq2>
Frequency two, which has a range of 0, 200-3200 Hz.
<dur>
Duration of the tone(s) in 10 ms units.
+VTX
Transmit Voice Samples.
Used for sending digitized voice samples from host memory through the
UART interface. The +VSM command determines the format of the sam-
ples. Multiple routing options are available.
