MSComm 控件通过串行端口(serial port)传送和接收数据,为应用程序提供了串行通讯功能。而且在可视化编程盛行的今天，可以很方便的在Visual Basic(VB)、Visual C++(VC)、Delphi等语言及开发平台中应用。-MSComm controls (serial port) to transmit and the receive data
through the serial port, has provided the serial communication
function for the application procedure. Moreover today which is in
vogue in the visible programming, may be very convenient in Visual
Basic (VB), Visual C (VC), language and so on Delphi and develops in
the platform to apply.
