A-72 NCR 5932-66xx Windows Configuration Utility
Note: The Sound Error Tone control code takes no parameters and disregards the
inputs for the frequency, volume, and duration parameters. When received by the
keyboard, it initiates an error tone with pre–configured frequency, volume, and
duration. The new tone immediately overrides the prior or existing tone.
Note: Key clicks or error tone can be disabled by setting key click duration to zero. Key
clicks are sounded on all keys except modifier keys (Control, Shift, and Alt). For more
information, refer to the “Keyboard Configuration Window” section in this chapter.
