HID Ignore Unknown Characters
This option applies only to the USB HID Keyboard 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 linear
imager scanner issues an error beep.
Emulate Keypad
When enabled, all characters are sent as ASCII sequences over the numeric keypad. For example, ASCII A is
sent as "ALT make" 0 6 5 "ALT Break."
