Hi all, I need your guidance here.

I have done my program of decoding AT keyboard scancode. Basicly it prints out scancodes whatever key I pressed.

I have also a handheld barcode scanner (Birch CCD-108e) with keyboard wedge connector.

I think the scanner protocol is the same as AT keyboard protocol, since the scanner use "keyboard wedge".

BUT...
I can't get the scanner connected to my '51.
The first time I turned the power on, the scanner is jammed.

What did I miss?

Regards,
Fahmy
