    • A designated byte of a PS/2 packet is used for data not recognized by a conventional PS/2 port driver. Each packet byte received by the conventional port driver is read by an Interrupt Service Routine (ISR) of a filter driver. If a received packet contains an unrecognized data type, that data is extracted. The filter driver converts the byte containing the data to 0000 0000. The port driver provides the all-zero byte to a higher level driver for processing into a subsequent data structure. A Service Callback Routine of the filter driver receives that data structure from the higher level driver. Depending upon the type of unrecognized data extracted by the ISR, that data is then either inserted into the data structure or passed independently of that data structure to a user level application.
    • PS / 2数据包的指定字节用于传统PS / 2端口驱动程序未识别的数据。 由传统端口驱动器接收的每个分组字节由过滤器驱动程序的中断服务程序(ISR)读取。 如果接收到的分组包含无法识别的数据类型,则提取该数据。 过滤器驱动程序将包含数据的字节转换为0000 0000.端口驱动程序将全零字节提供给更高级别的驱动程序,以便处理后续数据结构。 过滤器驱动程序的服务回调例程从较高级别的驱动程序接收该数据结构。 根据由ISR提取的无法识别的数据的类型,该数据然后被插入到数据结构中,或者独立于该数据结构传递给用户级应用。
