首先，分别对8255、8253进行初始化，设置8255为A口、C口输出，设置8253的计数器0为工作模式3；其次，设置IRQ7的中断矢量，使得有IRQ7中断时调用SERVER；再次，调用INIT对计数值初始化；最后，主程序循环等待中断，开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine

在屏幕上开出三个窗口：起止坐标为（5，10）和（15，30），（5，50）和（15，70），（18，15）和（22，65）。要求可用左右方向键选择左窗口或右窗口
在屏幕上开出三个窗口：起止坐标为（5，10）和（15，30），（5，50）和（15，70），（18，15）和（22，65）。要求可用左右方向键选择左窗口或右窗口为当前活动窗口。当一行字符显示满后（左右窗口一行显示20个字符，下窗口显示50个字符），窗口自动向上卷动一行，输入的字符仍显示与最低一行，窗口最高一行向上卷动后消失。用上下方向键可使活动窗口及下窗口内容同时上卷或下卷。输入‘ESC’后结束程序。(huangyujie)-screen out three windows : starting and ending coordinates (5,10) and (15, 30), (5,50) and (15.70) (18.15) and (22.65). Asked about the direction keys can be used to choose the left or right window to window to window current activities. When his characters show after the expiration of (his show window about 20 characters, the next window displays 50 characters), the window automatically scrolling upward here, the importation of characters showed that the minimum here, his highest window scrolling upward disappeared. Up and down direction keys enable activities under the window and window content, but on the next volume or volumes. Importation "ESC" end after the procedure. (Huangyujie)
