Using the Modem
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, click Properties to set connection speeds, or on
the Dialing Rules tab click 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 “Modem Reference Information” on
page 137.
Open Phone and Modem Options in Control Panel. On the Modems tab, click
Properties. You can type AT commands on the Advanced tab in the space for extra
settings.
For example, to force a built-in modem to turn off its speaker, you can use the M0
command as shown in table of AT commands—type ATM0 in the space for extra
settings.
