将实验箱232通信的接收端与发送端短接，P1.0接一个发光二极管，编写串口自发自收（查询方式）通信程序，检查本单片机的串口是否完好，如果发送字符与接收字符一致，则P1.0亮一秒灭一秒闪亮；否则，P1.0熄灭。设fosc=11.0592MHz，波特率为9600。要求用定时器T0实现1S的延时。

-Shorted to the experimental box 232 receiving end of the communication with the sender, P1.0 by a light-emitting diode, preparation of serial spontaneous self-closing (query mode) communication program, check the serial port of the microcontroller is intact, if you send and receive characters consistent P1.0 bright one second off one second shiny　Otherwise, P1.0 extinguished. Let fosc = 11.0592MHz, a baud rate of 9600. The 1S delay requirements timer T0.
