一个用8255的串口编程

此书是在BCB环境下开发串口通信的一本好书啊。文中详细讲解了串口通信的基本概念，同时很具体的描述了编写的过程并附有源码。-book is the BCB development environment Serial Communication a good book ah. This paper gave a detailed account of the serial communication the basic concept, but very specific description of the preparation process together with the source code.
