已知甲、乙两台80C51单片机所使用的晶振均为11.0592MHz。现要求两机之间进行串行通信，甲机发送，乙机接收。传输波特率定为9600。甲机片内以50H为数据起始地址的16字节数据发送给乙机。甲机首先发送数据长度，然后开始发送数据。乙机以接收的第一字节作为接收数据的长度，第2字节开始为数据。乙机将接收的数据存放在以60H为起始地址的16个单元内。编程计算直线与窗口边界所在直线的交点，直线端点和交点在Cohen-Sutherland直线段剪裁算法中的区域编码，

画出窗口及窗口内的直线段。-Known A, B two 80C51 microcontroller crystal are 11.0592MHz. Are now required for serial communication between the two machines, A sends B to receive. Baud rate set at 9600. A dryer sheet to 50H of the data start address 16-byte data is sent to the machine B. A machine first transmission data length, and then begins to transmit data. B machine length of the received data, the second byte as the first byte of the received data. Machine B will receive the data stored in the unit 16 as a starting address 60H. Programmed to calculate the intersection of the straight line and the boundary of the window where the straight line, the end of the line and the point of intersection in the Cohen-Sutherland line segment cut algorithm regional coding, draw a line segment within the window and the window.
