与中断矢量设置与读取有关的DOS功能调用，本例演示了如何编写中断服务程序，如何安装（将中断服务程序的地址设置到中断矢表中），以及如何通过软中断指令调用中断服务程序。为了突出重点，本例中中断服务程序代码未驻留内存。-and vector interrupt settings and read the DOS function calls, which in this case demonstrated how to prepare interrupted service procedures, how to install (to be interrupted service procedures set up to address the interruption vector table), and how soft interrupt directive calling service interruption program. To highlight key issues, in this case the interruption of services not the presence of code memory.

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
