| Abstract: | In distributed Computers the USB is an intelligent communication board based on RS422A/232C, which can be used for system booting, diagnosis and exceptional handling. Based on the USB, thispaper gives some ideas of hardware and software design. It can be seen that USB hardware supportsbit-oriented and asynchronous transfer protocol while its software applies store and forward method. |
