+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.
