except for unknown characters. No error beeps sound. When Do Not Send Bar Codes With Unknown
Characters is selected, for IBM devices, bar codes containing at least one unknown character are not sent to
the host, and an error beep sounds. For USB Keyboard HID devices, the bar code characters up to the
