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.
Open Phone and Modem Options in Control Panel. On the Modems tab, select
Properties. You can type AT commands on the Advanced tab in the space for
extra settings.
