VB Modbus的例子

serial.h serial.cpp 共两个文件，VC串口封装API类-serial.h serial.cpp a total of two documents, VC serial API Class Packaging

一个简明的串口通讯例子-a simple and clear example for serial port communication

本代码是VC源代码，实现通过串口接收和发送短消息。-VC code is the source code to achieve through the serial port to receive and send short message.

随着Windows98的推出，越来越多的微机用户已习惯于Windows操作系统。不过Windows应用软件的开发对于一般工程技术领域的技术人员来说并非易事，然而使用微软的VisualBasic6.0（简称VB6）来开发这些方面的Windows应用软件就十分方便，编程工作量相对较小，只需进行主要应用功能的编程和少量界面控制的编程。本文介绍利用VB6串行通信编程的方法对采用了RS-232接口的仪器,进行串行通信的计算机测控软件开发和实现仪器功能和指标的验收。-With the launch of Windows 98, more and more computer users are accustomed to Windows. But Windows application software development for the general area of engineering and technology and technical personnel is not easy, but to use Microsoft Visual Basic 6.0 (VB6) to the development of these applications on Windows is very convenient, programming workload is relatively small, only major applications programming a small amount of control and interface programming. This paper describes the use of VB6 serial communication programming method used to the RS-232 devices, serial communication control computer software development and the achievement of equipment functions and targets of acceptance.
