Based on Windows 9x operating system platform, a method of developing software logic analyzer by using virtual device driver is proposed and the corresponding software is developed. Software logic analyzer is mainly used to debug and reverse design PC expansion cards and other peripherals, the basic function is to capture a long continuous drive software to the hardware device issued by the I / O port operating instructions. Describes how it works and outlines its capabilities
