Abstract
A method for negotiating keyboard commands between a computer and an external keyboard is provided. The computer and the external keyboard have respective NL (number lock) status. When the external keyboard is pressed, the external keyboard act as the following mechanics. When NL status of the computer is “Off” and NL status of the external keyboard is “On”, and a time internal between adjacent serially-pressed numeric keys of the external keyboard is less than a predetermined time period, a key code of NL on the external keyboard is firstly sent to alter NL status of the computer from “Off” to “On”, key codes of pressed numeric keys of the external keyboard are secondly sent to the computer, and the key code of NL on the external keyboard is finally sent to alter NL status of the computer from “On” to “Off”.
