USB Ignore Unknown Characters
This option applies only to the HID Keyboard Emulation device and IBM device. Unknown characters are characters the host does not
recognize. When Send Bar Codes With Unknown Characters is selected, all bar code data is sent except for unknown characters,
and no error beeps sound. When Do Not Send Bar Codes With Unknown Characters is selected, bar code data is sent up to the
first unknown character, then the scanner issues an error beep.
