To change port settings

  • 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 Device Manager, click Start, click Control Panel, double-click Administrative Tools, double-click Computer Management, and then click Device Manager.

  • Most hardware devices that use ports set the port speed automatically. The defaults for modem port speed are specified in Phone and Modem Options in Control Panel.

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.
