用串口类实现VC与MCS51单片机之间的通信

Communication between VC and MCS51 by serialport class

通过对Visual C++与RS-232串口通信的若干方法的比较．阐明了用串口类的优点．并通过简易的数字可存储示波器的制作,详细说明了利用串口类实现Visual C++与51单片机之间的通信的全过程．

Through the comparison of multiple methods of serial communication between Visual C ＋ ＋ and RS -232, the advantage of serial class is clarified. And through the making process of simple digital savable osillograph, the process of implementing the communication between Visual C ＋ ＋ and MCS51 is particularly illuminated using serial class.
