Command options:
#VSS? Returns the current setting of the #VSS command as an ASCII
decimal value in result code format.
#VSS=? Returns the message,"0-3".
#VSS=0 Disables silence detection by the modem when in Voice Receive
Mode.
#VSS=1 Least sensitive setting. When this command is received by the
modem, the system is configured to a state which is least
likely to be the best overall compromise on normal telephone
lines.
#VSS=2 Midrange setting(default). When this command is received by
the modem, the system is configured to a state which is likely
to be the best overall compromise on normal telephone lines.
#VSS=3 Most sensitive setting. When this command is received by the
modem, the system is configured to a state which is most
likely to detect and compress periods of silence.
AT#VTD? DTMF Tone Reporting
This command queries and controls which types of tones can be detected
and reported to the DTE via shield codes in Voice Transmit, Voice
Receive, and Online Voice Command Modes.
Parameters: i,j,k (three ASCII hexadecimal bit maps)
Default: 3F,3F,3F
Result Codes: OK If bits supported with #VTD=? are selected.
Command options:
#VTD? Returns the current setting of the #VTD command as an ASCII
decimal value in result code format.
#VTD=? Returns the tone reporting capabilities of the modem.
#VTD=i,j,k Where i,j,k corresponds (in ASCII hexadecimal) to the
desired capabilities, as shown below, for Voice transmit,
Voice Receive, and Online Voice Command Modes,
respectively.
Bit Description
0 0 = Disable DTMF tone capability
1 = Enable DTMF tone capability
1 0 = Disable V.25 1300Hz Calling tone capability
1 = Enable V.25 1300Hz Calling tone capability
2 0 = Disable T.30 1100Hz Facsimile Calling tone capability
1 = Enable T.30 1100Hz Facsimile Calling tone capability
3 0 = Disable V.25/T.30 2100Hz Answer tone capability
1 = Enable V.25/T.30 2100Hz Answer tone capability
4 0 = Disable Bell 2225Hz Answer tone capability
1 = Enable Bell 2225Hz Answer tone capability
5 0 = Disable call progress tone and cadence capability
1 = Enable call progress tone and cadence capability
6-7 Reserved
AT#VTS Generate Tone Signals (Online Voice Command )
This action command can be issued to play one of more DTMF or other
tones (such as a "beep") if and only if the modem is in the Online
Voice Command Mode. The modem parses and plays the tones defined in
the parameter in the order listed, and no key abort is accepted. The
parameter can have three types of elements separated by commas:
Dual or Single Tones: These are represented by a substring enclosed in
square brackets ("[]") with in the parameter.
Each such substring consists of three
