    Here are the different ways to play / sound tones:

     

    To play a standard message beep, you can use the IDA command

     

    function doIDABeepOK()

    {

        external.CETerm.PostIDA("IDA_BEEP_OK", 0);

    }

     

    To play a loud beep, you can use the IDA command

     

    function doIDABeepLoud()

    {

        external.CETerm.PostIDA("IDA_BEEP_LOUD", 0);

    }

     

    To sound a tone, you can use the Playtone interface of the OS object and provide volume, frequency and duration as input parameters. The same interface can be sequenced with variations in the input parameters to sound complex tones. For the Playtone interface

         * volume is 00 -10 (0 is off, 10 is loudest)

         * frequency is in Hz.

    duration is in milliseconds.

        external.OS.PlaySound( "infbeg.wav", 0);

        external.OS.PlaySound( "infend.wav", 0);
