Description: 串行通信MCS-51单片机内部有一个全双工的串行通信口，即串行接收和发送缓冲器（SBUF），这两个在物理上独立的接收发送器，既可以接收数据也可以发送数据。但接收缓冲器只能读出不能写入，而发送缓冲器则只能写入不能读出，它们的地址为99H。这个通信口既可以用于网络通信，亦可实现串行异步通信，还可以构成同步移位寄存器使用。-MCS-51 microcontroller serial communication within the a full-duplex serial communication port, that is, the serial receive and send buffer (SBUF), these two physically separate receiver transmitter, both can receive data can be sent data. Only read by the receiving buffer can not write, but can only write to send the buffer is not allowed to deliver, their address is 99H. The communication port can be used for both network communications, can also achieve the serial asynchronous communication, but also constitute a synchronous shift register to use.

Description: 单片机接收从电脑串口发送出来的一串字符串，却只能接收到第一个字符，其他的都丢失了或者是接收到的是乱码，却不知道是什么原因。其实，那是因为，虽然单片机的是全双工串口，但是串口的缓冲区(SBUF)却一般只有一个字节，即1Byte，远没有像电脑串口的缓冲区以KB计算那么大，并且，单片机的处理速度是很有限的，试想一下，假如要求一串字符串以9600bps的速率，一个起始位，一个结束位，无校正位，相当于960Byte/s传输到单片机，单片机要是能够全部接收的话，那么单片机接收和处理一个字节的时间仅为约1ms的时间。这说明了，如果单片机的处理速度不够快，还没有将接收到的上一帧数据及时转送到单片机的RAM中，而电脑串口又传输过来一帧新的数据，这帧新的数据就会把单片机的串口输入缓冲区的SBUF给刷新掉，或者说单片机压根就没有接收到新的一帧数据，造成了数据的丢失或接收到乱码。
