串口通讯经典程序

说明：  这是我自己写的关于串口通讯的小程序,适于两台PC机之间通过(交叉串口线)串口通讯.可以(自动或手动)发送数据、接收数据、保存数据。是调试串口和初步学习串口编程的好例子。其中还用到了典型的串口类，对于从事串口编程者有一定的借鉴作用。
(that I write on small serial communication procedures, suitable for two between the PC (cross-Serial Line) serial communications. May (automatically or manually) to send data, receive data, the data is preserved. Serial debugging is a preliminary study and Serial Programming good example. It also uses the typical serial category, for those engaged in serial programming is useful role.)
