More Information
Summary:The invention relates to a method and a system for intercepting and capturing port data in a Win9x operation system. The method comprises the steps of: creating a log file corresponding to a port in a kernel mode; utilizing VxD driver program in the Win9x operation system, intercepting and capturing each operation request aiming at the port, judging whether the operation requests are reading/writing requests or not, if so, storing data to be read/written by the reading/writing requests to the log file corresponding to the port, and then, executing the reading/writing requests; and otherwise, executing the operation requests. When the technical scheme of the method and the system is utilized, the cost for intercepting and capturing the port data is reduced on the premise without applying and releasing the port use right.
