Specifications and Regulatory Information Modem Reference Information Modem Reference Information Note If your computer has a built-in modem, you can customize the operation of the modem using AT commands and S-registers. You can do this from Modem (Windows 98) or Phone and Modem Options (Windows 2000 or XP) in Control Panel, from most communications software, or by using terminal mode in your software. See "To change your modem settings" on page 66. You should have a good understanding of modems and how they operate before you change default settings.
