| Abstract: | It can indirectly access I/O ports by calling Vxd under kernel state to increase its safety. The core structure of Windows is discussed. The model and implementation principle of kernel state device driver are discussed too. The method and implementation process to access I/O ports based on Vxd are intensively analyzed and program example about parallel interface control is given. |

| Keywords: | kernel state Vxd VM I/O Request Package |
