Description: 目前普遍采用的MCS51 和PIC 系列单片机通常只有一个（或没有）UART
异步串行通信接口，在应用系统中若需要多个串行接口（例如在多机通信系
统中，主机既要和从机通信又要和终端通信）的情况下，通常的方法是扩展
一片8251 或 8250 通用同步/异步接收发送芯片（USART），需额外占用单
片机I/O 资源。本文介绍一种用单片机普通I/O 口实现串行通信的方法，可
在单片机的最小应用系统中实现与两个以上串行接口设备的多机通信

Description: 1，正如有的朋友所说，这是丁丁原作的改版(并无冒犯丁丁之意)；
2，向丁丁学习，源程序公开，不过上位机界面(VB做的)暂时还不舍得(哈哈)；
3，源程序框架便于大家扩展支持的芯片(编好了别忘了给我一份)，上位机部分用数据库；
4，上下位机的通讯规约源程序里有简单说明，双击下边的组合框能看到发送的报文；
5，公开的动机：受晓奇无私精神感动，也是想得到高手(尤其是版主)的指点批评；
6，硬件增加了发送指示灯、四角增加了大面积焊盘用于焊上四个脚(比如用螺母)；
7，软件修正了原不能打开16K以上HEX文件的错误，更大规模的文件可能还有问题；
8，另外，好多朋友问我原理图中的TL521是什么，其实应该是：TLP521-1(光偶)。-err
