DTMF and Tone Generation: This command causes the modem to generate
DTMF tones or pulse tones in voice mode. The code aborts the play-
back of tones, sends the “OK” result code, and returns the modem to the voice
command state. The DTE/DCE inactivity timer is in place during tone production.
The command +VTS sent without a parameter assumes the default value, which
is a null string. The DTE may use the -shielded code to refresh the
timer.

m= The is made up of a list of and parame-
ters. is in units of Hz, and is in units of 0.01 seconds.

The tone string consists of up to three types of elements: a single ASCII charac-
ter, a string in brackets, and a string in braces. Commas must separate the ele-
ments. Missing elements assume the value of zero. The following list explains
each element and how it can be used.
