    To Do this

    Change the speaker volume, maximum port speed, or wait for a dial tone before dialing.

    Click the Modem tab.

    View diagnostic information, including commands supported by your modem, or to view a log of modem activity.

    Click the Diagnostics tab.

    Add extra initialization commands.

    Click the Advanced tab.

    Change call preferences (manual dialing or disconnecting) or data connection preferences (port speed, data protocol, compression, or flow control).

  • 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.

  • Not all default configurations in the connection interface are secure. Ensure that you change settings appropriately.

Information about functional differences

  • 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.
