【Abstract】 Serial interface possesses the good qualities of connecting simply, using conveniently and data transfering credibly, so it has gained abroad appliance in real\|time control system. In this paper, the method of serial communication’s programming with Microsoft Communication Control in the Windows 98 platform is discussed, the approach of serial communication’s programming which is based on the technique of ActiveX in C++ Builder5.0 is expatiated. The method is simpleness and credibility. It can shorten programming period greatly and reduce the work of the programmer.更多还原
