摘要
分析了ＤＯＳ管理外设的四个层次和ＤＯＳ的控制功能，指出ＤＯＳ的控制功能可以用于标准外设的管理，使用文件句柄的文件功能也通常用于驱动外设，同时还说明了ＤＯＳ对非标准外设进行管理的三种方法：ａ）Ｉ／Ｏ重定向：即外设的操作通过文件句柄和保留设备名来实现；ｂ）可安装的设备驱动程序：非标准设备驱动程序安装后通过文件句柄操作；ｃ）非标准设备的驱动程序可用保留设备名ＡＵＸ或ＰＲＮ编写或用扩展的软件中断处理程序编写。
Four hierarchies for DOS operating system to manage peripheral devices are analyzed. The control functions of DOS are emphatically analyzed. The control function is provided for the standard peripheral devices. File functions using filer handler are also applied to operating the peripheral devices. Especially, three methods for DOS dealing with the non-standard peripheral devices are explained as follows: a) I/O re-direction: The operation of peripheral device is implemented by File Handler and the reserved name of devices. b) Installed Device Driver: After the device driver is installed for the non-standard device, the device is operated by Filer Handler. c) Non-standard device driver can be written by using the reserved name of device AUX or PRN or by expanding a new software interrupt.
