这是一个串口通信的队列,单片机和电脑之间，单片机和单片机之间只要简单的调用函数就可以了。-This is a serial communication queue, single-chip computer and between computers, between single-chip MCU and a simple function call it.

51单片机的FIFO(先入先出)循环队列实现（已在串口通信中实际应用）-51 single-chip FIFO (FIFO) circular queue (already in the practical application of the serial communication)
