摘要: A data processing apparatus receives key codes corresponding to keys depressed on a plurality of keyboards. These key codes are sequentially stored in a first-in first-out (FIFO) buffer awaiting processing by a central processing unit (CPU). If successive key code entries correspond to an auto repeat key (e.g., a space key, a backspace key, an underline key, a move cursor key, etc.), a determination is made whether the auto repeat key codes are the same. If they are, the CPU processes the subsequent auto repeat key code. If they are different, the CPU ignores that auto repeat key input. In another embodiment of the present invention, one of the keyboards is hardwired to the data processing system while a second keyboard is connected via a wireless link. Auto repeat key codes are only accepted from the first wire-connected keyboard, and any auto repeat key codes from the second wireless keyboard are ignored.
