一个外国人写的rs485串口通信程序，有原理图和源代码，全面实现了485协议...

用于串口应用程序的调试监控工具，软件可模拟设备往串口发送指定格式的数据串，同时也可以用于实时监控串口读写过程中的所有数据流。☆ 自动侦测当前系统中所有可用的串口数，支持USB扩展出的虚拟串口（可到COM256）。☆ 支持ASCII码和十六进制数据格式的发送和接收。☆ 可以自由选择侦测的串口，接收数据区的容量可以无限大。☆ 发送、接收数据区的大小可以随意拉伸调节。☆ 对发送、接收数据区加入鼠标右键菜单的支持。☆ 扩大串口波特率的支持，现最高Baud可到921600。☆ 支持Unicode内码显示。☆ 增加自动发送数据功能。☆ 增加保存显示记录的功能。-applications for serial monitoring of debugging tools, software can simulate serial devices to send data to the specified format string, but also can be used for real-time monitoring serial process of reading and writing all data stream. automatically detect the current system all available serial number, support USB expansion of Virtual Serial Port (available to COM256). support ASCII and hexadecimal format of the data to send and receive. freedom of choice to detect the serial and receive data in large capacity can be unlimited. send and receive data of arbitrary size can adjust tension. right to send and receive data by adding areas of the right mouse button menu support. serial port baud rate of expansion, is

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.
