这是在w2000和winxp下直接访问IO断口的驱动源码，我们可以用该驱动来直接访问并口。-This is the w2000 and winxp direct IO fracture visit the driving source, We can use that to drive directly to the parallel port.

通过PortTalk和改良的函数集、在Windows 2000 和 Windows XP 下进行IO口的直接访问。主调函数为OpenCurrentProcessIOAllAccess(PID: THandle)或者OpenCurProcessIOAllAccess(CurWnd: THandle)，PID为进程ID，CurWnd为窗口句柄。-through PortTalk and improved function set. In W
