MSComm控件资料,Visual Basic 6.0(以下简称VB) 是一种功能强大、简单易学的程序设计语言。它不但保留了原先Basic语言的全部功能，而且还增加了面向对象程序设计功能。它不仅可以方便快捷地编制适用于数据处理、多媒体等方面的程序，而且利用ActiveX控件MSComm还能十分方便地开发出使用计算机串口的计算机通信程序。本文结合计算机通信的两个例子，详细介绍如何在VB中使用MSComm控件。 处理方式 -MSComm information, Visual Basic 6.0 (VB hereinafter) is a powerful, relatively simple programming language. It not only retains the original Basic language functionality, but also an increase of object-oriented programming design functions. It will not only facilitate the efficient preparation of the application to data processing, multimedia and other aspects of the procedure, and the use of MSComm ActiveX control can be very convenient to use the computer to develop the computer serial port Communication Program. Based on computer communication, the two examples in detail how to use VB MSComm. Approach

该程序是不占用资源的串口数据捕捉.同一台计算机中,再有其他应用程序或设备同时占用一个或多个串口的情况下,捕捉这些串口的通信数据,显示在界面上,并可保存-that the procedure was not occupied resources serial data capture. Same computer, we have other applications or devices occupying one or more serial circumstances, the capture of these serial data communications, and display the interface and can be preserved

这个是8253芯片的两个实例程序，对学习接口的人是有一定帮助的-this is the 8253 case of two procedures, to learn the interface are certainly helpful

实现两台机器之间的串口通信！可以对串口进行调试！-achieved between the two machines serial communications! Can serial debugging!

用vb实现串口间通信,可以用来熟悉串口间传输信息的原理.-with Serial Communication, which can be used with serial transmission of information between the principle.
