Method for controlling switch of input mode of keyboard instructions
First Claim
1. A method for controlling switch of input mode of keyboard instructions, comprising:
- a) Requesting no specified state of a main keyboard and an auxiliary keypad;
b) Using a program of said keypad to read and put status flag of said main keyboard and said keypad for remembering present respective state thereof; and
c) Pressing an arbitrary key of said keypad, whereby the program of said keypad will compare whether the status flag of said main keyboard and said keypad are identical or not;
if positive, a key code to be sent out is acceptable, otherwise, a Num Lock code will be sent to a host frame of a notebook computer for changing the state of said main keyboard into that of said keypad for receiving a key code from said keypad;
after the key code is transmitted, the program is to send the Num Lock code again to the host frame for restoring the state of said main keyboard while said keypad remains its state unchanged;
therefore, despite of the original state of said main keyboard and said keypad, controlling switch of input mode of figures or characters will become easier and more convenient without causing interference between said main keyboard and said keypad.

Abstract
A method for controlling switch of input mode of keyboard instructions is to provide and load a program to intellectualize an auxiliary keypad without forcing any of or both the keypad and a main keyboard to retain at a specified state. In other words, the program of the keypad will read the present status flag of the keypad and the main keyboard and put them in memory. Hence, when an arbitrary key of the keypad is pressed, the program will compare whether the state of the keypad and the main keyboard are identical or not; if positive, a key code from the keypad is acceptable, otherwise, a Num Lock code will be transmitted to a host frame of a notebook computer for changing the state of the main keyboard into that of the keypad for receiving a key code from the keypad. After transmission of the key code to the host frame, the program will send the Num Lock code again to the host frame for restoring the state of the main keyboard while the keypad remains its state unchanged.
