用8251a实现串行口异步通信，自发自收，波特率1200bps，采用查询方式发送，中断方式接受。自收结果显示于屏幕。按esc返回dos -8251a Serial port with asynchronous communication, spontaneous self-income, the baud rate 1200bps, using queries sent, interrupt to receive treatment. Since the close results showed on the screen. Press esc to return dos

此程序为KEIL环境下开发的代码（开发环境备选里没有KEIL），功能在成功运行后可以播放“生日快乐”歌。所需要的开发硬件为AT89C51为主芯片的单片机。-This program is developed under the code in KEIL environment (development environment, where there is no alternative KEIL), features a successful running play " Happy Birthday" song. Required the development of hardware-based chip microcontroller AT89C51.
