    • A method and system to recognize input events from a plurality of input devices. Each input device is coupled to a device driver or similar device specific code and a recognition provider. Upon attachment to the system, the recognition provider registers the known input events which the input device is capable of transmitting at the recognition subsystem. The recognition subsystem sends an identifier back to the recognition provider for each registered input event. When the recognition provider receives one or more input signals from the input device which are recognized as an input event, the provider sends the identifier to the recognition subsystem. The input event is transmitted to a process running on the system which may interpret the input event or request translation by the recognition subsystem. The invention is useful to introduce new input devices to a system without requiring modification of the existing processes.
    • 一种识别来自多个输入设备的输入事件的方法和系统。 每个输入设备耦合到设备驱动器或类似的设备特定代码和识别提供者。 在附接到系统时,识别提供者注册输入设备能够在识别子系统处发送的已知输入事件。 识别子系统为每个注册的输入事件向识别提供者发送标识符。 当识别提供者从输入设备接收被识别为输入事件的一个或多个输入信号时,提供者将识别符发送到识别子系统。 输入事件被发送到系统上运行的进程,其可以解释输入事件或由识别子系统请求转换。 本发明对于将新的输入设备引入系统是有用的,而不需要修改现有的过程。

    • A system is disclosed for managing a plurality of interrupt handlers in a linked-list data structure, for servicing a plurality of input/output devices sharing a common interrupt line in a microcomputer. The system provides for an orderly method to link a newly loaded interrupt handler routine into a linked-list data structure consisting of previously loaded interrupt handler routines. The system further provides for an orderly method to share a common interrupt line among a plurality of input/output devices being serviced by the interrupt handlers. The system further provides for an orderly means to unlink a particular interrupt handler routine from the linked-list data structure when a corresponding input/output device is to be deactivated. The system finds special utility in a multitasking operating system environment where input/output devices can be deactivated in a different sequence from that in which they were originally activated.
    • 公开了一种用于管理链接列表数据结构中的多个中断处理程序的系统,用于维护在微计算机中共享公共中断线的多个输入/输出设备。 该系统提供了一种有序的方法来将新加载的中断处理程序例程链接到由先前加载的中断处理程序例程组成的链表数据结构中。 该系统进一步提供一种有序的方法来在由中断处理程序服务的多个输入/输出设备之间共享公共中断线。 当相应的输入/输出设备被去激活时,该系统进一步提供一种有序的方法来将特定的中断处理程序例程与链表列表数据结构断开连接。 该系统在多任务操作系统环境中找到特殊的实用程序,其中输入/输出设备可以与其最初激活的序列不同的顺序禁用。
