To Change Your Modem Settings
The modem is already set up to be compatible with telephone
systems and modems in most areas. However, in some situations,
you may have to change modem settings to match local
conditions. If you have questions about local requirements,
contact your telephone company.
■ Control Panel. Open Phone and Modem Options in Control
Panel to change many modem settings. On the Modems tab,
select Properties to set connection speeds, or on the Dialing
Rules tab, select Edit to set dialing options.
■ Communications software. Many communications
applications provide options for controlling modem settings.
See the Help for your software.
■ AT commands. You can control many aspects of modem
operation using modem AT commands. AT commands are
special strings of characters sent to the modem to set up
specific conditions. Those command strings normally start
with
“AT.” For a list of AT commands for the built-in modem,
see the “Reference Information” chapter.
From the Control Panel, select Phone and Modem Options.
On the Modems tab, select Properties. You can type AT
commands on the Advanced tab in the space for extra
settings.
