急，急！如何用vxd来设计数据采集卡的中断和端口读写

请问，如何用vxd来设计数据采集卡的中断和端口读写，最好用vtoolsd.谢谢了，我急着用。

说来话就长了。
1. Use VPICD_Virtualize_IRQ() to \"install\" a IRQ Handler in device init.
   2. Use VPICD_Phys_Unmask() to clear mask, now interrut will be handled by your handler. In your handler, before return, you must
   3. Use VPICD_Phys_EOI() to send a EOI(End Of Interrupt) to PIC, otherwise error occurred!
   4. Use VPICD_Force_Default_Behavior() to \"Unistall\" a IRQ Handler in device exit, before it, must use VPICD_Phys_Mask().

vtools下面有一个hwint的例子，可以参阅着修改
