If you have Microsoft Windows 3.0 or 3.1
----------------------------------------

Use Microsoft Windows to run the SETUP.EXE program as documented in
your Users Guide.  The SETUP.EXE Windows program will properly install
and configure your ESP card.

   Uninstall Feature
   -----------------

   A last minute feature added to the SETUP.EXE program is an option to 
   Uninstall your ESP card.  This allows you to remove the ESP's COM 
   port from the system map and clean up any changes made to the 
   SYSTEM.INI and WIN.INI files.

   How to Uninstall
   ----------------
   If you wish to Uninstall a card or a particular port, use 
   Microsoft Windows to run the SETUP.EXE program.  The first window
   you see is the 'Card Configuration' window. To uninstall, select
   the address of the card and press the 'Configure' button.  The
   'Modify Card Configuration' dialog box will appear.  Go to the right hand
   corner of the dialog box and press the 'Uninstall' radio button.  After
   pressing the 'Uninstall' button, go down to the 'Ok' button to save
   the new configuration.  This brings you back to the 'Card Configuration'
   window press the 'Exit and Save' to uninstall the card.   

If you do not have Microsoft Windows 3.0 or 3.1, but you do have DOS
you can use DOSSETUP.EXE or ESPCA.EXE.  ESPCA.EXE is a command line 
oriented configuration program.  If you need assistance in configuring 
the ESP adapter use DOSSETUP.EXE, which provides help screens on each 
configuration option.   

   DOSSETUP.EXE
   ------------
   A DOS setup program, DOSSETUP.EXE, has been included that allows you to 
   configure the ESP Communications Accelerators for your system.  Run the 
   program from the DOS prompt and select an ESP card to configure.  The 
   Address, Port, and IRQ information for the selected card will then be 
   displayed.  Use the arrow keys to select the parameter you wish to change.
   (Note: For new installations and for cards which have been uninstalled, 
   the information displayed represents suggested values and not the 
   information on the card).

   DOSSETUP.EXE also allows you to select one-time settings (set for the
   current session of DOS only).  These are:

        1) FIFO Enabling for all ESP2 cards in your system.
        2) Automatic RTS/CTS Flow Control for the currently selected card.
        3) UART Baud Rate Multiplier Prescale Value for the selected card.

   To access these options, select 'Other Settings...' from the Address/
   Port/IRQ configuration screen.

   For every option in DOSSETUP, help text is displayed at the bottom of
   the screen to assist you in configuring your ESP2 card.  DOSSETUP will
   also detect other serial cards and their IRQs to inform you of possible 
   conflicts.


   ESPCA.EXE
   ---------
The ESPCA.EXE program runs under DOS, and can configure your ESP
Communications Accelerator card.  

Type ESPCA ? at the DOS prompt to receive help on how to use ESPCA.EXE.
The ESPCA program will display:

Usage: ESPCA F Axxx:yyy Cxxx:y Ixxx:y Rxxx:y Pxxx:y S Q

       ?          - display this usage information
       F          - initialize all ports to FIFO enabled
       Axxx:yyy   - change I/O address xxx to yyy
       Cxxx:y     - change COM designation for port at I/O address xxx to y
       Ixxx:y     - change IRQ for port at I/O address xxx to y
       Rxxx:y     - enable (y='+') or disable (y='-') RTS/CTS flow control
       Pxxx:y     - set UART baud rate multiplier prescale value (y=0-3)
       Uxxx       - uninstall I/O address (all ports on board)
       S          - skip read configuration step if possible
       Q          - quiet (no screen output)

   I/O Addresses

   Each ESP card must have its own I/O Address, and is referred to by that
   address (the xxx values above).  The ESP card is factory-configured to use
   I/O Address 300 (hex) when the hardware jumper is in the S/W position.

   You may change the I/O address by moving the hardware jumper from its
   factory position S/W to the 140, 180, or 280 positions.

   If a different I/O address is desired, use the Axxx:yyy command to store
   a new S/W address in the ESP card's permanent (nonvolatile) memory.  I/O
   Addresses 100, 140, 180, 200, 240, 280, 300, and 380 are available.
   For example, to change the ESP card from its factory I/O address of 300 to
   I/O address 100, type ESPCA A300:100.

   Each port on an ESP card has a unique I/O address.  The I/O addresses for
   subsequent ports on a card are multiples of eight.  For example, on a
   two-port ESP card, the first port is referred to by I/O address 300, and
   the second port is referred to by I/O address 308.

   Note that these I/O addresses are different than UART I/O addresses (which
   are associated with COM ports, and have values like 2F8 and 3F8).

   COM and IRQ Designations

   You will want to choose a COM designation which does not conflict with an
   existing port.  For example, if your PC has a built-in COM1 serial port,
   you should designate the ESP port as COM2.

   COM ports require IRQ assignments.  There are de facto standard IRQ
   assignments based on COM port choice.  These are:

        COM1    IRQ4
        COM2    IRQ3
        COM3    IRQ4
        COM4    IRQ3

   To assign COM3 and IRQ4 to the ESP card, type ESPCA C300:3 I300:4
   (assuming your ESP card is at the factory I/O address of 300).

   Note: IRQ conflicts can occur if more than one card attempts to use a given
   IRQ number at the same time.

   FIFO Enable

   Use the F switch to enable extended 1024-byte FIFOs on the ESP card when
   used in UART mode (1024-byte FIFOs are always used in Enhanced Mode).
   Enabling the larger buffers often results in increased performance and
   reliability compared to standard 16-byte 16550A FIFOs.

   You may wish to include the line:

   ESPCA F S

   in your AUTOEXEC.BAT file to enable the larger FIFOs automatically at boot
   time (the S switch skips the sometimes lengthy "read configuration" step).

   RTS/CTS Automatic Flow Control

   The ESP Communications Accelerator can perform automatic hardware RTS/CTS
   flow control.  You may wish to disable software for "no flow control 
   Xon/Xoff" if you plan to let the ESP card perform automatic flow
   control.

   To enable RTS/CTS automatic flow control, type ESPCA R300:+ (assuming your
   ESP card is at the factory I/O address of 300).

   Baud Rate Prescaler

   Your ESP Communications Accelerator can communicate at speeds higher than
   115,200 bps using the P command, which multiplies baud rates.  Baud rates
   can be doubled, quadrupled, or octupled.  The maximum data rate is 8 times
   115,200, which is 921,600 bps.  Prescale values range from 0 to 3 as 
   follows:

      0 - 1x baud rates (normal baud rates)
      1 - 2x baud rates
      2 - 4x baud rates
      3 - 8x baud rates

   To set an ESP port for maximum speed, type ESPCA P300:3 (assuming your
   ESP card is at the factory I/O address of 300).

   Uninstall Port

   If you wish to disable all ports on a card, or a particular port, use the
   U command to set the COM designation to COM0 (disabled).  Specifying the
   lowest I/O port address for a multiport card disables all ports for that
   card, for example:

   ESPCA U:140          (disables all ports on card with I/O Address 140)


   Skip Read Configuration

   The ESPCA.EXE program reads the configuration information from the ESP
   card's nonvolatile memory each time it runs in order to display the
   information.  This step takes several seconds to complete.  If you do not
   want to take the time unless necessary, specify the S switch.

   Quiet Mode

   Specifying the Q switch results in Quiet Mode, under which the ESPCA.EXE
   program will produce no standard output.


INSTALLING THE CORRECT WFW 3.11 COMM.DRV FILE

   The COMM.DRV file is in a compressed format on Disk 2 of your
   Microsoft Windows for Workgroups (TM).  The name of the compressed
   file is COMM.DR_.

   Copy COMM.DR_ from the floppy to your Windows 'SYSTEM' directory. 
   For example if Windows is installed on C:\WINDOWS, then the system 
   directory would be C:\WINDOWS\SYSTEM.  Your copy command would
   be:
       COPY [x:]COMM.DR_ C:\WINDOWS\SYSTEM.

   After you make the copy then go to that directory and expand the
   file.  An example of the commands to do this is as follows:

       CD\WINDOWS\SYSTEM
       EXPAND COMM.DR_ COMM.DRV

   The EXPAND program is part of your DOS installation and can be found
   in your DOS directory.
