data except for unknown characters. The device issues no error beeps.
Select Do Not Send Bar Codes With Unknown Characters, for IBM devices, to prevent sending bar codes
containing at least one unknown character are to the host, or for HID Keyboard Emulation devices, this sends the
bar code characters up to the unknown character. The device issues an error beep.
