Method for sending a keycode of a non-keyboard apparatus

A method for sending a keycode of a non-keyboard apparatus, comprising the steps of:

• (a) connecting the non-keyboard apparatus to a computer so as to perform device enumeration and generate enumeration information, wherein the enumeration information is recorded by the non-keyboard apparatus;
• (b) setting information related to the kind of an operating system, and recording the information by the non-keyboard apparatus;
• (c) sending a first keycode to the computer by the non-keyboard apparatus at a sending time, and recording the sending time by the non-keyboard apparatus, wherein the first keycode is selected from the group consisting of a keycode corresponding to the Num Lock key, a keycode corresponding to the Caps Lock key or a combination of two of these;
• (d) feeding back to the non-keyboard apparatus, by the computer at a feedback time, that a first key corresponding to the first keycode is enabled, and recording the feedback time by the non-keyboard apparatus;
• (e) reading the sending time and the feedback time, and calculating a time elapsed therebetween so as to produce a computer efficiency parameter, wherein the computer efficiency parameter is recorded by the non-keyboard apparatus;
• and
• (f) reading the kind of the operating system so as to determine a preset second keycode that matches the kind of the operating system, wherein the second keycode includes a plurality of key characters;
• and reading the computer efficiency parameter so as to determine a time interval at which the key characters are to be sent, wherein the second keycode is an ASCII (American Standard Code for Information Interchange) code.
