ABSTRACT:
A method for managing the input codes from the keyboard and the point device and an apparatus thereof are provided. When the computer system is not coupled to a PS/2 mouse and a hybrid keyboard is found to be connected to the computer system, the method first requests the hybrid keyboard to send a leading code designated to the pointing device. Afterwards, the method detects whether an input code from the hybrid keyboard has a leading code. And if there is a leading code, the method emulates the input code as a PS/2 mouse code and sends the emulated PS/2 mouse code to the computer system.
