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.

  • This value is usually set correctly when the modem is installed.

  • This speed represents the maximum speed programs are allowed to transmit data to the modem and is normally faster than the modem speed. For example, this is usually set to 57,600 bps for a 33.6 Kbps (V.34) modem.

  • Changing this setting also sets the current speed for the modem. To set a different value for the current speed, see Related Topics for the procedure to change the data connection preferences.

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.
