Making Connections
Using the Modem
66 Corporate Evaluator’s Guide
To dial in to a network
You can use the modem to dial in to a LAN (local area network) that supports dial-in
connections. This gives you access to network resources from a remote location.
•
See Windows Help for information about setting up and using dial-in network
connections—click Start, Help (or Help and Support).
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 Modems (Windows 98) or Phone and Modem Options
(Windows 2000 or XP) in Control Panel to change many modem settings.
For Windows 98, on the General tab click Properties to set connection speeds or
special dialing options.
For Windows 2000 or XP, 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” and contain
additional characters. For a list of AT commands for the built-in modem, see
“Modem Reference Information“ on page 169.
For Windows 98, open Modems in Control Panel. On the General tab, click
Properties, then on the Connection tab click Advanced. You can type AT commands
in the space for extra settings.
For Windows 2000 or XP, 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 the built-in modem to connect with V.34 modulation, you can use
the +MS command, as shown in the table of AT commands—type AT+MS=11 in the
space for extra settings.
