Voice Commands
ComStar SVD supports the following voice commands in
response to the AT#CLS=8 command, which sets the voice/audio
mode. Commands marked with an asterisk (*) will function only in
this mode. Others will be recognized in any mode (data, Class 1
fax, Class 2 fax, or voice/audio).

A
Answering in voice/audio mode.
D

H
Hang up in voice/audio mode.
Z
Reset in voice/audio mode.
#BDR=0
Enables autobaud detection on the DTE interface
#BDR=
n
Forces baud rate for 1<
n<48 (turns off autobaud), where
the speed is defined as
n×2400 bps. For example, if n=1,
speed is 2400 bps; if
n=48, speed is 115,200 bps.
#CID=0
Disables Caller ID.
#CID=1
Enables formatted Caller ID reporting.
#CID=2
Enables unformatted Caller ID reporting.
#CLS=0
Selects data mode.
#CLS=1

seconds). The default is 10 (one second). If n=0, tone

#VCI?*
Requests the compression method and raw bits/sample.
#VLS=0*
