+VTD, Tone Duration

This command handles the selection of tone duration. An integer <n> defines the length of tones
emitted as a result of the +VTS command. This command does not affect the D (dial) command.
(Refer to "D, Dial Command", page 13.)
Any value other than zero causes a tone of duration <n> in multiples of 100 msec.
In this command, the new value is erased after power down.
