Method and device for two-way communication between virtual PS/2 apparatus and host machine

Abstract

The invention is a method and device for virtually making two-way communication between PS / 2 equipment and host computer, and the method includes the steps: 1) PS / 2 equipment-end MCU virtually makes the communication of the host computer with the PS / 2 equipment; 2) host computer-end MCU virtually makes the communication of the PS / 2 equipment with the host computer. The device comprises PS / 2 equipment and host computer and besides, comprises a fist MCU at the PS / 2 equipment end, used to virtually make the host computer interchanging the initializing signal of the PS / 2 equipment with the PS / 2 equipment, initialize the PS / 2 equipment and detect and process PS / 2 equipment-end PS / 2 protocol communication signal; and comprises a second MCU at the host computer end, used to virtually make the PS / 2 equipment interchanging the initializing signal of the PS / 2 equipment with the host computer, virtually initialize the PS / 2 equipment by the host computer and detect and process host computer-end PS / 2 protocol signal. Because of using the MCU to virtually make the communication between the PS / 2 equipment and the host computer, the invention can support the startup of the host computer without equipment and the hot plug of the PS / 2 equipment, and can adopt enlarge the communication distance between the PS / 2 equipment and the host computer in a RS485-protocol communicating mode.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and device for realizing virtual communication in a computer. Background technique [0002] The computer is the product of the rapid development of modern society. Its appearance not only facilitates people's life, but also improves people's work efficiency. As an important auxiliary function device of the computer, the PS / 2 device communicates with the host computer through the PS / 2 protocol interface. Described PS / 2 protocol interface refers to the interface formulated according to the PS / 2 protocol standard, PS / 2 equipment such as keyboard, mouse can be connected with host computer and realize the mutual communication between host computer and PS / 2 equipment by PS / 2 protocol interface communication. [0003] In recent years, with the development of some special application fields, such as the development of server management system, there are new requi...
