  4. KNOWN LIMITATIONS

     After installing a new device in Windows ME, please reboot
     your system for the ports to become accessible.

     The Device Manager incorrectly reports bogus resources for
     each of the RealPort serial ports (see the Ports (COM & LPT)
     category of the Device Manager). This is a limitation of the
     operating system, which requires that serial ports are
     associated with a physical address space, albeit phantom.

     If you plan to use the RealPort driver with serial printers,
     you may want to reboot the system after device installation or
     after renaming ports to see the new ports listed in the Print
     Spooler's list of available ports. This is a known limitation
     of the Print Spooler, which does not detect changes in the
     list of available ports automatically.

     If you experience difficulties operating serial printers, try
     enabling the option, "Complete write requests immediately."
     A checkbox of the same name can be found in the port's Port
     Properties dialog in the Device Manager.

  5. INSTALLING THE REALPORT DRIVER

     To install the driver, follow these steps:

     o Close the Device Manager if it is running.

     o Unzip the driver archive to a folder of your choice.

     o Run DIGIRPCL.BAT to remove any previous INF file versions.

     o Open Start > Settings > Control Panel.

     o Locate and run the control panel named "Add New Hardware".

     o Windows indicates that it will next search for new Plug and
       Play devices, which may take a few moments. Choose "Next >"
       to continue.

     o If Windows finds any new Plug and Play devices for which it
       has installation files, it will install them and will
       complete the Add New Hardware Wizard. If this happens, rerun
       the Add New Hardware Wizard. Otherwise, Windows may find
       some devices for which it doesn't have installation files
       and will list them now.

     o Tell Windows the device you want to install isn't listed by
       selecting the radio entitled, "No, the device isn't in the
       list." Choose "Next >" to continue. (This dialog does not
       appear in Windows Me.)

     o Windows allows you to search for non-Plug and Play
       compatible devices. Select instead the radio, "No, I want to
       select the hardware from a list," and choose "Next >".

     o Windows displays a list of hardware categories. Select
       "Other devices" and choose "Next >" to continue.

     o Windows will display a list of known hardware in the
       category previously selected. Don't select any device from
       the list. Instead, choose "Have Disk..." to point Windows to
       the location of the installation files.

     o Enter the path to the installation files. Choose "OK".

     o Windows now searches the indicated directory for
       installation files and displays a list of devices it can
       install. Find your device in the list, select it, and choose
       "Next >."

     o Choose "Finish" to continue the installation.

     o The RealPort driver will now ask for the device's I.P.
       address and TCP port. Enter this information and choose
       "OK" to complete the installation. You can change this
       information later via the Device Manager.

  6. UPDATING THE REALPORT DRIVER

     To update the driver, follow these steps:

     o Close the Device Manager if it is running.

     o Unzip the driver archive to a folder of your choice.

     o Run DIGIRPCL.BAT to remove any previous INF file versions.

     o Next, open the Device Manager:

        - Open Start > Settings > Control Panel.

        - Run the control panel named "System".

        - Click the "Device Manager" tab.

    o Find and open the "Multi-port serial adapters" category.

    o Display the properties dialog for the device you would like
      to update.

    o Click the "Driver" tab.

    o Choose "Update Driver..." to run the Update Device Driver
      Wizard.

    o Choose "Next >".

    o The default radio button should be selected, "Search for a
      better driver than the one your device is using now."
      Choose "Next >".

    o Deselect all radio buttons.

    o Select the radio button entitled, "Specify a location:".

    o Enter the path to the updated driver files (the directory
      to which you unpacked the archive) or click "Browse..." to
      graphically search for and select the directory.

    o Choose "Next >" after you have entered the directory path.

    o The Update Device Driver Wizard now suggests a driver to
      install, albeit the wrong driver. Select instead the radio
      button entitled, "One of the other drivers."

    o Choose "View List..." to display the list of other drivers.

    o Choose the proper device description from the list (the
      description should match the description of the device
      being updated). Choose "OK".

    o Choose "Next >".

    o Choose "Next >".

    o The driver will prompt for the I.P. address and TCP port of
      the device. The values previously used by the device should
      already be entered by default. Choose "OK" to continue.

    o Choose "Finish" to complete the update.

  7. ADDITIONAL NOTES

     On-line help is available after installing the product.

     Additional documentation can be found at Digi's Web site,
     http://www.digi.com, or at Digi's FTP server, ftp://ftp.digi.com.

     ALLOW PORTS TO BE OPENED WHEN NETWORK IS UNAVAILABLE
     ----------------------------------------------------

     Turn this feature on if you want the RealPort driver to
     always succeed open requests, even if the driver cannot
     communicate with the remote device at the time of the open.
     By default, the driver only succeeds an open request if it
     can communicate with the remote device.
