  5. UPDATE DRIVER

     You need administrative privileges to update device drivers. 
     Please be sure you are logged into Windows as Administrator 
     or as a user that is a member of the Administrators group.

     To update an existing AccelePort RAS driver, first perform these 
     steps:

     1. Unzip the driver installation package to a folder of your 
        choice.
     2. Run Dgaxcln.cmd to remove previous Inf file versions.

     Next, locate and follow the instructions for your specific
     operating system:

     WINDOWS 2000

     a. First, navigate to the Device Manager and locate the device
        whose device driver is to be updated:

     6.1 Digi PortAssist Manager
     ---------------------------
       This driver's PAM communication agent uses UDP Port 2364.

       PAM Server to use this port number instead of the default.

       instructions.
