本文介绍VB6.0利用MSComm通信控件，开发微机通过串口对工业仪表进行实时数据采集的编程技术。给出的程序代码具有通用性，并有详细的注释，可以直接或稍加改动后用于其他数据采集或实时控制程序中。-This article describes the use VB6.0 MSComm communication control, the development of industrial computer through the serial port data acquisition instrumentation for real-time programming techniques. Given program code is versatile, and there are detailed notes, or a little change can be directly used for other data collection or after the real-time control program.
