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 138.

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.
