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) in Control Panel, from most
communications software, or by using terminal mode in your software. See "To change
your modem settings" on page 57.
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, which is included with selected models of
the HP notebook PC:
If your computer has a LAN port and a modem port, you have a 3Com modem.
If your computer has a modem port but no LAN port, you have an Ambit modem.
