Barcode readers can be supported either by the standard X protocol, or through the X input device extension. In either case, there has to be device-dependent code in the X server that can receive input from the device and generate X events. Hewlett-Packard X servers running on our workstations do support a barcode reader. The HP92916A Barcode reader has two modes, one that causes it to generate ASCII data, and the other that causes it to emulate a keyboard. It can be used in addition to, or instead of, a keyboard. It can also be accessed though the X input extension. I don't believe that any X terminals available from HP support barcode readers.
