Modem Reference Information

If your computer has a modem port, you can customize the operation of the modem using
AT commands and S-registers. You can do this from Modem (Windows ME or 98) or
Phone And Modem Options (Windows 2000) in Control Panel, from most
communications software, or by using terminal mode in your software. See “To change
your modem settings” on page 63.

You should have a good understanding of modems and how they operate before you
change default settings.

This section contains summary information about AT commands, S-registers, and
selected result codes for the built-in modem. Your computer has either a US Robotics or
Ambit (ESS) modem. To determine which brand is in your computer:

•

  Click Modems (Windows 98) or Phone and Modem Options (Windows 2000) in

Control Panel.
