+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 11.)

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.

Note: In GSM, the tone duration value can be modified depending on the specific network.
