众所周知，C++Builder本身并不提供串行通讯控件MSComm，但我们却可以通过注册后直接使用它。启动C++Builder5.0后，然后选择C++Builder主菜单中的Component菜单项，单击Import Active Control命令，弹出Import Active窗口，选择Microsoft Comm Control6.0，再选择Install按钮执行安装命令,系统将自动进行编译,编译完成后即完成MSComm控件在C++Builder中的注册,系统默认安装在控件板的Active页,接下来我们就可以像使用C++Builder本身提供的控件那样使用新注册的MSComm控件了。（前提条件是你的机子上安装了Visual Basic，或者有它的库）

-known, C Builder itself does not provide serial communication MSComm control, but we can be registered directly use it. Activated C Builder5.0, then select C Builder main menu of Component menu item, click Import Active Control Order Import Active pop-up window, select the Microsoft Comm Control6.0 and choose Install button to install the implementation of orders, the system will automatically build, compile completed MSComm be completed in the C Builder registration, the system's default installation of the control board's Active pages, we can then use as C Builder itself as the control of the use of the new registration of MSComm. (Prerequisite is the machine you installed Visual Basic, or the library)
