51单片机串口通讯设计代码公开，

//这是一个单片机C51串口接收（中断）和发送例程，可以用来测试51单片机的中断接收

//和查询发送，另外我觉得发送没有必要用中断，因为程序的开销是一样的

-51 design code serial communication open,// ??this is a C51 microcontroller serial receiver (interrupt) and send routine can be used to test the microcontroller interrupt reception 51// and the query is sent, and I feel no need to use interrupt transmission, because procedure is the same as the cost of
