USART_InitStructure.USART_BaudRate = 9600; 
        USART_InitStructure.USART_WordLength = USART_WordLength_8b; 
        USART_InitStructure.USART_StopBits = USART_StopBits_1; 
        USART_InitStructure.USART_Parity = USART_Parity_No ; 
        USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None; 
        USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx; 

        USART_Init(USART1, &USART_InitStructure); //初始化串口
        USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);//开启中断
        USART_Cmd(USART1, ENABLE);                    //使能串口 

        USART_WakeUpConfig(USART1,USART_WakeUp_IdleLine);// 空闲总线唤醒
        USART_ReceiverWakeUpCmd(USART1,ENABLE);          //使能接收唤醒 

        串口设置如上所示，但是串口没有一点进入静默的意思，依然能够接收到数据。不知道是不是还有那里没设置对，请高手指点一二。
