Description: 本章提供于Windows 操作系统设计Modbus 通信程序所需的基本子程
序，以Borland C++ Builder V5.0 所设计的Sample Porgram 提供读者参考。
所有原始档（source program）都存于随书赠送的光盘片内。读者必须了
解通信程序是需要高度与操作系统的API 相配合，各种资料型态的转换，
Multi-Thread 的运用，时间的掌控等事项，以C 语言为最适合的语言。-This chapter in the Windows operating system designed to provide Modbus communication program required for the basic subroutine to Borland C++ Builder V5.0 is designed to provide readers Sample Porgram reference. All the original files (source program) are stored in the book with free CD-ROM chip. Readers must understand the communication procedures with the operating system requires a high degree of matching of the API, a variety of data types conversions, Multi-Thread the use of control over matters such as time to C language is the most suitable language.
