单片机C51串口中断接收和发送测试例程可以用来测试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
-80C51 Serial interrupted receive and send test routines can be used to test 51 MCU interrupt reception// Send inquiries and, I also think that this is not necessary for discontinued because the process is the same as the overhead
