Notes

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open a Control Panel item, click Start, click Control Panel, and then double-click the appropriate icon.
Type the commands exactly as they should be sent, with no extra spaces or characters. The AT prefix is unnecessary.
The commands you enter here are sent after the standard initialization commands for the selected modem. This enables you to change the modem behavior or configuration as required by your communication software or to communicate with a service provider. For more information about the commands recognized by your modem, refer to the manufacturer's documentation or Web site.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
