     DRIVER INSTALLATION NOTES FOR PCI ADAPTERS
     ------------------------------------------

     After installing one of the above adapters and booting the
     machine, Windows will automatically install an older 
     version of the device driver. This version of the driver is 
     included as part of Windows, and it can also be found on 
     the Windows CD.

     The Update Driver functionality available via the Device
     Manager is not supported, however. Instead, to upgrade the
     existing device driver for any of the above adapters, please 
     follow these steps:

     a. First, uninstall the previously installed device driver.
        From the Device Manager, expand the catagory "Multi-port
        serial adapters". Right-click on the Digi adapter(s) you 
        would like to uninstall from the system and select 
        "Uninstall".

        Be sure to uninstall each adapter that needs to be 
        upgraded.

     b. Run the program Dgclean.cmd to move the existing INF files
        for the adapter. This ensures that the new driver files 
        will be installed instead of the old driver files. 
        Dgclean.cmd is part of the driver software package and can
        be found in the same directory as the new driver files.

     c. Tell Windows to scan for new hardware. From the Device 
        Manager, right click and select "Scan for hardware changes".
        The "Found New Hardware Wizard" should appear.

        Alternatively, one may reboot Windows to conjure the 
        "Found New Hardware Wizard".

     d. Follow the instructions for the "Found New Hardware 
        Wizard". From the "Locate Driver Files" screen, be sure 
        to select "Specify a location" to point the wizard to the 
        location of the new driver files.

     e. Windows will display a "Digital Signature Not Found" 
        message, explaining that the driver is not signed.  Click 
        "Yes" to continue the installation. One may see several of
        these warnings -- simply click "Yes" for each message to 
        proceed with installation.
   
     f. Follow any other instructions to complete the installation.
   
     g. The "Found New Hardware Wizard" may reappear a number of
        times depending on the number and type of adapters you are 
        installing.

         Digi AccelePort Xe EIA-232 ISA         
         Digi AccelePort Xe EIA-232/422 ISA     
         Digi AccelePort Xe EIA-232/422 ISA      
         IBM 8-Port Async EIA-232/RS-422A PCI      
         IBM 128-Port Async PCI           
     o Added Port Settings property page.
     o Fixed blue screen in Windows Server 2003 when the Xem
       adapter is installed without any modules attached.
     o Fixed missing event viewer descriptions for several 
       message ids.
     o Removed install wizard page for Xr 920 adapters. 
     o Fixed TransmitCommChar() handling - driver was 
       allowing multiple simultaneous requests.
     o C/X adapter was accepting a baudrate it couldn't 
       handle - 921600 baud.

     Version 4.2.45.0 (Rev. C, December 21, 2003)
     ---------------------------------------------------
     o Fixed problem with ClearCommError misinterpreting 
       breaks and reporting too many bytes in cbInQueue.
     o Fixed a multiprocessor system lock-up when making

       utilization to extremes.

       resulted in intermittent adapter deadlock when setting
       the baud rate.

     Version 4.1.38.0 (Rev. B, May 05, 2003)
     ---------------------------------------
     o Added support for Microsoft Windows Server 2003
     o The following adapters are no longer supported by this driver:
         Digi AccelePort 4r 920 ISA
         Digi AccelePort 8r 920 ISA
         Digi AccelePort 4r EIA-232 ISA/PCI
         Digi AccelePort 8r EIA-232 ISA/PCI
         Digi AccelePort EPC/X ISA
         Digi PC/4e ISA
         Digi PC/8e ISA
         Digi PC/16e ISA
         Digi PC/8i ISA
         Digi PC/16i ISA
     o Fixed EV_RXFLAG handling when EV_ERR is also requested.
     o Modified parity, framing, and break error detection such
       that events are now reported before the client issues a
       read request.
     o Fixed intermittent problem with too many characters being 
       reported in the receive queue.
     o Fixed two ring events being generated instead of just one.
     o Fixed an inaccurate ring buffer head pointer value used to
       copy received data from the adapter to the driver.  This
       gave the appearance that the data in the ring buffer had
       wrapped around, giving us a unusually high received byte
       count and bogus data.
     o Fixed a race on multi processor systems: one CPU inaccurately
       reported a count of characters in the receive buffer which 
       included characters that the other CPU was simultaneously 
       removing.
     o Added RTS toggle support for Xem, Xr, and Xr 920 adapters.
     o Fixed RTS toggle to not slew character after dropping signal.
     o Improved compatibility with standard serial driver.
     o Fixed initial port settings to default to 1200,7,e,1 for
       proper Plug & Play modem detection.
     o Changed "Complete writes when transmit complete" feature 
       to default to on.
     o Modified port open and set baud rate procedures to prevent
       race condition when multiple ports are opened simultaneously.
     o Fixed problem upgrading AccelePort Xr EIA-232 adapter
       driver from Windows 2000 to Windows XP or Windows .NET.

     Version 4.0.21.0 (Rev. A, February 13, 2002)
