−repeat value
Specifies the number of times an action will occur when the terminal or workstation bell sounds.  The default value is 1.

−suppress milliseconds
Specifies the length of time that must pass between bell events. If a bell event occurs within the specified suppress time after a previous bell action, it will be ignored.  The default suppress time is 200 milliseconds. 

The following options support indicator modes:

−refresh [ −refreshColor color ] [ −refreshGeom geometry ]
Causes a screen refresh, which appears as a flashing of the screen.  If you include the −refreshColor option, you can specify a color to be used in the refresh action.  If you include the −refreshGeom option, you can specify the portion of the screen to be refreshed. 

−command [ −prog command ]
Causes a command to be executed whenever a bell event occurs. Use the −prog option to specify the command you want to be executed. 

−bitmap [ −fg color ] [ −bg color ]
Displays a small sound icon window that flashes whenever a bell event occurs. Use the −fg and −bg options to specify the foreground and background colors for the icon window.
