    • A signal from a remote control is used to operate a device having a built-in communication port and a built-in microprocessor, even though the port does not normally recognize the signal. Specifically, even if the port flags an error during decoding of information from the remote control signal, the microprocessor ignores the error and uses the decoded information in the normal manner. Therefore, the microprocessor recognizes a pattern formed at the communication port by a signal emitted by the remote control, e.g. to identify a button on the remote control that has been pressed. During the recognition process, the port flags one or more errors (such as framing error, parity error), and such errors are ignored by the microprocessor. Programming the microprocessor to ignore errors from the port allows the device to operate with signals in a format different from the format normally recognized by the port. When use of the remote control is completed, the device may be returned to normal operation, wherein erroneous information is rejected.
    • 来自遥控器的信号用于操作具有内置通信端口和内置微处理器的设备,即使端口通常不能识别信号。 具体地说,即使端口在从遥控信号解码信息期间标记错误,微处理器忽略错误,并以正常方式使用解码的信息。 因此,微处理器通过由遥控器发出的信号,例如,识别在通信端口处形成的图案。 识别遥控器上按下的按钮。 在识别过程中,端口标记一个或多个错误(如成帧错误,奇偶校验错误),并且这些错误被微处理器忽略。 对微处理器进行编程以忽略来自端口的错误,允许器件以与端口通常识别的格式不同的信号进行操作。 当遥控器的使用完成时,设备可以恢复正常操作,其中错误的信息被拒绝。
