Examples
- The second chapter describes the hardware design of the protocol converter that is based on the rabbit 2000 microprocessor . in the third chapter , the software design method of the protocol converter that is developed by the dynamic c language is presented in detail . the fourth chapter is the experiment and applications part
第二章对基于rabbit2000微处理器开发设计的用以完成rs232串行通讯端口协议与tcp江p协议协议转换功能的协议转换器的硬件设计进行了详细描述，第三章对采用dynamicc语言开发设计的协议转换器的软件设计进行了详细描述。 - First this chapter analyses the function of modem in theory , as well as communication principle of computer and modem . second designs program of serial communication using mscomm of vb 6 . 0 , by reason that mapbasic is the second development tool of mapinfo and a programmable language of developing map information applications , it is unable to directly read datas of serial port used by modem , unless by means of external program . finally using dde technology completes transmitting real - time orientation data between mapinfo and serial communication program of vb
本章首先从理论上分析了modem功能及与计算机的通信原理；其次利用v86 . 0的通信控件mscomm开发串行程序，由于mapbasic是mapinfo二次开发工具，是一种编制地图信息应用程序的编程语言，不能直接读取串行通讯端口数据，它必基于gsm网和pstn网的移动终端和远程主机的实时数据通信系统的技术研究须借助外部程序来完成与modem的串行通讯；最后利用ode技术来实现maplnfo与vb串行通信程序实时定位数据传输。
