用VB进行串口实时数据采集，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。-Using VB serial real-time data acquisition, communication paper introduces VB6.0 using MSComm control, through the serial port on the computer industry to develop real-time data acquisition instrumentation programming techniques. Program code given is universal, and there are detailed notes, either directly or after little change for other real-time data acquisition or control program.
