就是用串口通讯线将两台机子用串口连起来进行通讯，最简单的。比如在a机上输入一个字符，在b机上能显示出来 -Serial communication is to use two machines will be used for serial communication link, the most simple. For example, in a plane into a character, b plane will display

modbus是应用比较多的通讯协议，程序计算MODBUS RTU通信协议中的CRC校验-Modbus is the application of a relatively large number of communication protocols, procedures MODBUS RTU communication protocol computing the CRC checksum

利用NI的动态链接库编写的GPIB通信实例，能够初始化8920A测试仪器，能够发送相关的控制命令来控制仪器的工作状态，还能够读取仪器的测试数据，采用标准的gpib32动态链接库，程序通过耐久性测试，在断电之后再通电仍然能够不用关闭软件而直接连接通信。之前是vc的例子调用，在此改为了利用delphi调用相关函数，发送相关控制命令一样实现了delphi的gpib通信程序。

上位机做客户端，来读取下位机设备的数据。其中通讯协议是基于modbus的TCP/IP协议，用socket套接字来实现数据的传输。

基于vc得串口通信助手的源程序，对于高通信的兄弟有帮助。-source code of serial communication based on visual C++. it s very helpful to those interested in communication.
