Device Commands

Devices—hard disks, printers, video displays, keyboards, and modems, for example—can supply input to the computer, receive output from the computer, or both. This chapter discusses the commands that control the devices connected to your computer. You use these commands to redirect input and output, select alternative keyboards, and print graphics and text files.

DOS supplies many different commands to help you interact with devices. With three commands referred to as filters, DOS is responsible for channeling information between devices. You can use these filters—MORE, FIND, and SORT—to modify information as it passes from files to the screen. Table 13.1 lists and explains the functions of the commands and filters discussed in this chapter.
