串行接口通讯试验该试验可以学习如何编写一个通讯程序。这个试验能够实现的功能很简单，仅仅作为试验用。工作环境为：无需其余任何环境，直接接通电源即可。-serial communication interface test of the pilot can learn how to prepare a communication process. The pilot function can be achieved is very simple, just to experiment with. The working environment : the environment without any rest, can be directly connected to power.
