+VTS=m none
DTMF and Tone Generation: This command causes the modem to generate
DTMF tones or pulse tones in voice mode. The <DLE><!> 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 <DLE><NUL>-shielded code to refresh the
timer.
m=<string> The <string> is made up of a list of <freq> and <duration> parame-
ters. <freq> is in units of Hz, and <duration> 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.
