本书第一部分讲述的是传统的网络接口N e t B I O S、重定向器以及通过重定向器进行的各类 网络通信。尽管本书大部分内容均围绕Wi n s o c k编程这一主题展开，但是， A P I比起Wi n s o c k 来，仍然具有某些独到之处-book on the first part of the traditional network interface N e t B I O S, Redirector and through Redirector for the various network communication. Although most of the contents of the book revolves around Wi n s o c k program this topic, but A P than I Wi n o c k"s, still has some special gifts

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.

控制信号由接收机的通道进入信号调制芯片，获得直流偏置电压。它内部有一个基准电路，产生周期为20ms，宽度为1.5ms的基准信号，将获得的直流偏置电压与电位器的电压比较，获得电压差输出。最后，电压差的正负输出到电机驱动芯片决定电机的正反转。当电机转速一定时，通过级联减速齿轮带动电位器旋转，使得电压差为0，电机停止转动。当然我们可以不用去了解它的具体工作原理，知道它的控制原理就够了。就象我们使用晶体管一样，知道可以拿它来做开关管或放大管就行了，至于管内的电子具体怎么流动是可以完全不用去考虑的。-Control signal from the receiver into the signal modulation of the channel chip, access to the DC bias voltage. It has a base internal circuit, resulting in a period of 20ms, the base width of 1.5ms signal, will be the DC bias voltage and the voltage comparator potentiometer to obtain the output voltage difference. Finally, the positive and negative output voltage difference to the motor driver chip motor positive decision. When the motor speed must, through the reduction gear drive cascading rotary potentiometers, the voltage difference is 0, motor to stop rotating. Of course, we do not have to understand the principle of its work, the control principle to know its enough. As we use the same transistors that can switch it to do or to enlarge
