the AT%T21 command.
2. Issue an ATZ command.
3. Issue an ATS11? command to display the new value. The following example shows how to set the current
default value from 80 to 85:

ATS11?

If you do not want to change both par#5 and par#6, set par#5 to the new default DTMF duration if you are
increasing the default value from the current value; otherwise, set par#6 to the new default DTMF duration.
