3.13 +VTD Tone duration
Description
This refers to an integer <n> that defines the length of tones emitted as a result
of the +VTS command. This does not
affect the D command. A value different than zero causes a tone of duration
<n>/10 seconds. The value zero causes a
"manufacturer specific" value.

3.14 +VTS DTMF and tone generation
Description
This command allows the transmission of DTMF tones and arbitrary tones (see
note). These tones may be used (for
example) when announcing the start of a recording period. The command is
write only. In this profile of commands,
this command does not operate in data or fax modes of operation
(+FCLASS=0,1,2-7).
+VTS=
as above
Command
+VTS=? (list
Defined values
1. <DTMF>. 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.
NOTE 2: In GSM this operates only in voice mode.
2. [<tone1>,<tone2>,<duration>]. This is interpreted as a dual tone of
frequencies <tone1> and <tone2>,
lasting for a time <duration> (in 10 ms multiples).
NOTE 3: This does not operate in GSM.
3. {<DTMF>,<duration>}. This is interpreted as a DTMF tone of different
duration from that mandated by the
+VTD command.
3.15 +CLCC List current calls
Description
Returns list of current calls of MT. If command succeeds but no calls are
available, no information response is sent to
