                    ATABLET Mouse Driver V1.11
                    ==========================

This ATABLET.COM mouse emulator driver is used with software applications
which only support a Microsoft Mouse or Mouse Systems Mouse. This breakthrough
DOS driver also provides the look and feel of absolute positioning with many
advanced applications which allow a mouse device to work under absolute
positioning.

This driver also includes the functions of Real Mode ADI driver for
using with the AutoDesk DOS applications which support the Real Mode ADI
driver. With the ATABLET.COM mouse driver, you don't need another
Real Mode ADI driver any longer.

This feature is helpful for eliminating some interference problems if
you used to change the working environments between the DOS application
using mouse driver and the AutoDesk application using another Real Mode
ADI driver.

Refer to the manual of your DOS application(s) to configure the input 
device by choosing either Microsoft Mouse or Mouse Systems Mouse in the 
setup procedure of each application. Load ATABLET.COM (see below) before 
you start your DOS application. For some DOS applications, you will now 
be able to use the tablet as a mouse with the superior look and feel of 
absolute positioning. (NOTE: Some DOS applications do not support 
absolute positioning and force relative positioning as their default 
setting. With this in mind the default installation setting for 
ATABLET.COM is relative positioning.) 

Note!   The  ATABLET.COM driver is fully compatible with the current 
        release version of the Microsoft Mouse driver available at the 
        time of this documentations printing.

Once you load the ATABLET driver, it remains in memory until you reboot 
your computer or turn it off. If you load another mouse driver after 
loading ATABLET.COM, ATABLET.COM will be invalid.

If you want to load the functions of Real Mode ADI driver for using with
the AutoDesk DOS applications which support the Real Mode ADI driver,
please refer to the manual of your AutoDesk application(s) to configure
the digitizer by choosing the Real Mode ADI in the configuration menu or
by modifying the appropriate environment setting file. Before you start
the AutoDesk application(s), load the ATABLET.COM with optional parameter
(see below) to activate the Real Mode ADI functions.

If you load any other Real Mode ADI driver after loading ATABLET.COM,
the Real Mode ADI functions of ATABLET.COM will be invalid but leave
the mouse driver functions available for using with DOS applications.


Installing the ATABLET Driver
=============================

To install the ATABLET driver, please refer to the section - Installing
the Drivers Using Easy Auto-Install Program in the README.DOC file in
the root directory.

Note!   For your convenience in running our ATABLET Mouse driver, we 
        suggest you to allow our Auto-Install program to modify your
        AUTOEXEC.BAT file when you are prompted to do so.


Loading the ATABLET Driver
==========================

To load the ATABLET driver, type the following command and press <ENTER>.

        ATABLET  [/n] [/n] [... 

                where /n is an optional parameter(s) described below.

        Or

        Use a batch file, such as your AUTOEXEC.BAT to execute ATABLET.COM 
        and load the mouse driver. Insert the above command into your batch
        file.

ATABLET displays sign-on and status messages indicating the current 
parameter settings for Mouse mode, Transducer type, Button Assignments, 
COM port and Coordinate Mode each time it is executed.


Parameter Descriptions
======================

  Serial Port assignment - /#
  ---------------------------

        Assigns the port where the tablet is installed. /# selects the COM 
        port that the tablet is connected to.

        /1      -       Selects COM1 
        /2      -       Selects COM2
        /3      -       Selects COM3 
        /4      -       Selects COM4

        If a COM port is not specified, the driver will attempt to 
        automatically detect which COM port your tablet is connected to. 
        We recommend you setting the port assignment explicitly by using 
        this parameter.

   IRQ Number Setting - /I#
   ------------------------

        This parameter allows you to specify the IRQ number. The IRQ number
        is generally standard for each COM port (COM1 to COM4) for most
        serial I/O cards, so the user normally does not need to select the 
        IRQ number. If necessary, please refer to the manual of your serial 
        I/O card to select the exact IRQ number with the serial port assignment. 
        The IRQ number (#) is a decimal number in the range of 2 to 5.

   Coordinate Mode Setting - /A or /R
   ----------------------------------

        This specifies whether the driver communicates in Absolute or 
        Relative mode.

        /A      -       Specifies Absolute mode
        /R      -       Specifies Relative mode (default)

        If your DOS application does not support Absolute mode, the cursor 
        movement will still be in Relative mode even though the coordinate 
        mode in the driver is set to Absolute mode.

   Mouse Mode - /MS or /PC
   -----------------------

        This specifies whether the driver is set to be compatible with 
        Microsoft Mouse (2-button Mouse) or Mouse Systems Mouse (3-button
        Mouse).

        /MS     -       Sets the driver to Microsoft Mouse. (default)
        /PC     -       Sets the driver to Mouse Systems Mouse.

        If necessary, select the same Mouse device in the setup of your 
        DOS application by referring to the manual of the application. If 
        your DOS application supports only a Microsoft Mouse device, you 
        must set the driver to Microsoft Mouse (default). However, the 
        Middle button in the button assignments only applies to Mouse 
        Systems Mouse mode.

   Button Assignments - /B
   -----------------------

        The /B parameter allows you to select the transducer type you use 
        and the set of button assignments you want. When you load the driver
        with the /B option, the following table will appear on the screen.

                1.      2-button Stylus-Pen (default)
                2.      3-button Stylus-Pen
                3.      4-button Cursor-Puck
                4.      16-button Cursor-Puck
                (Press <Esc> to cancel)

                Enter your transducer type (1): _

        Enter  the number (1 to 4) to select the transducer type you use 
        and press <enter>. Then follow the directions on the screen to enter 
        a letter to select the new set of button assignments you want and 
        press <enter>.

        Note!   The selected transducer type and new set of button assignments
                will be saved to the driver for future use, so you do not need 
                to load the driver with the /B option every time. The factory 
                default set of button assignments in the driver is set  A for 
                2-button Stylus-Pen (Tip button is left click; Barrel button 
                is right button).

   Tracking Area - /C
   ------------------

        The /C parameter allows you to change the tracking area within the 
        whole active area of your tablet. The default tracking area is the 
        whole active area of your tablet (5"x5"). If you use the driver with 
        your application software under relative mode, we recommend that you 
        use the whole active area as the tracking area.

        If you can use the driver with your application software under 
        absolute mode, the position of the stylus-pen or cursor-puck on the
        tracking area corresponds directly to the screen position. If you are
        using the tablet primarily for menu picking and cursor movement, you 
        may wish to reduce the size of the tracking area. With a smaller 
        tracking area, you can move from one corner of the screen to the 
        other with a shorter distance on the tablet, substantially increasing 
        your speed and ease of work.

        To specify a new tracking area:

        1.      When you load the driver with /C option, the configuration 
                menu will appear on the screen, which shows the active area 
                rectangle, message area and five command buttons.

        2.      Use the left button to choose the CONFIG button. A dash-lined
                rectangle will appear in the lower-left corner of the whole 
                active area rectangle, and the position of the tablet's 
                pointing device (the X and Y coordinates) on the tablet will 
                appear on the lower-right corner of the screen.

        3.      Use the left button to click the lower-left corner of the new
                tracking area, which you want to use, within the dash-lined
                rectangle. Then click the upper-right corner of the new 
                tracking area.

        4.      Choose any one of the following command buttons;

                OK      -       Save the new tracking area to the driver and 
                                then load the driver.
                CANCEL  -       Cancel the new tracking area you chose. Load 
                                the driver with the  preset  tracking area.
                RESET   -       Restore the tracking area to the whole active 
                                area of the tablet.
                TEST    -       Test and try to use the new tracking area on 
                                the screen of the configuration menu.

   LCD Screen Update Skip Setting - /N#
   ------------------------------------

        This parameter is useful for some slower display systems. For example,
        LAPTOP Systems or NOTEBOOK Systems which incorporate an LCD display.

        The # is a decimal number in the range of 0 - 100 that specifies the
        threshold value for cursor drawing. The cursor is drawn on screen
        once the accumulated count value of transducer movement reaches the
        threshold value. Larger values will reduce the sensitivity of the
        driver. Default is /N0/.

   Text Cursor Lock Function - /O#
   -------------------------------

        This parameter allows the user to inhibit application programs 
        from modifying the cursor attribute on the screen when in text mode.
        When enabled, the cursor is locked to the default text cursor.

        /O1     -       Enable the cursor locked function
        /O0/    -       Disable the cursor locked function (default)

   Sensitivity Setting - /S#, /H# or /V#
   -------------------------------------
        This allows the user to change the tracking response in relative 
        mode. You may want to experiment to find a comfortable setting.

        /S      -       Specifies both Horizontal & Vertical Sensitivity in one
                        parameter
        /H      -       Specifies Horizontal Sensitivity
        /V      -       Specifies Vertical Sensitivity

        The # is a decimal number in the range of 1 - 100. Default value 
        is 50. Larger values result in a faster response and lower values are
        slower, great for highly accurate cursor pointing.

   Disable/Remove Driver - /OFF
   ----------------------------

        This parameter removes the resident portion of the driver from 
        system memory if possible, and disables driver functionality until 
        it is reloaded again.

        NOTE:   The driver cannot be physically removed from memory if
                another "memory resident" program has been loaded after 
                ATABLET. However, ATABLET is  still  disabled  (turned off)  
                with the /OFF parameter.

   Activate Real Mode ADI functions --- /ADION
   -------------------------------------------

        This parameter activate the Real Mode ADI functions for using this
        driver with AutoDesk application(s) which support Real Mode ADI driver.

        NOTE :  The Real Mode ADI functions use the system interrupt numbered
                79H of your computer (where H means the number is represented
                in hexadecimal notation).

   Deactivate Real Mode ADI functions --- /ADIOFF
   ----------------------------------------------

    This parameter deactivate the Real Mode ADI functions but the 
    mouse driver functions are still available for DOS applications.


Command Examples
================

*****   C:\>ATABLET /1 /A

        This command loads the ATABLET driver and sets it to communicate 
        with COM1 in Absolute mode.

*****   C:\>ATABLET /2 /N10

        ATABLET is loaded for COM2 in Relative mode (default), Sensitivity 
        of 50 (default), and a skip value of 10.

*****   C:\>ATABLET /OFF

        This disables ATABLET and removes it from resident memory, if 
        possible.

*****   C:\>ATABLET /3 /I5

        ATABLET is loaded for COM3 with IRQ number 5. 


Changing Parameters Once ATABLET Is Loaded
==========================================

Parameters may be changed after loading ATABLET by issuing another 
ATABLET command. For example, you may want to experiment with several 
different /S or /N values to determine the value you like best. The 
parameters can be combined in any order, except that Sensitivity 
parameters only work in Relative Mode and /OFF should be issued alone.


TROUBLESHOOTING
===============

Problem:        You configure the input device options of your DOS application
                for Microsoft Mouse or Mouse Systems Mouse, but the tablet
                cannot work with your DOS application.
Solution:       Please verify you already load the ATABLET mouse driver into 
                your computer properly before you start your DOS application.

Problem:        You cannot load the ATABLET mouse driver and an error 
                message appears.
Solution:       If the tablet is connected to COM3 or COM4, please also check
                whether the COM port and its IRQ number on your serial card
                are the same as the parameters used for the ATABLET driver.

Problem:        You use the tablet as a mouse with your DOS application. The 
                cursor responds to the movement of your tablet's pointing 
                device sometimes, but not always.
Solution:       Check to see if the tracking area is set for the full active 
                area. The tracking area is defined through the driver with 
                the /C parameter of the ATABLET mouse driver.

Problem:        You use the tablet as a mouse with your DOS application. 
                Button functions are not correct in your application software.
Solution:       Please check that the set of button assignments loaded with 
                the ATABLET mouse driver is what you want. Also, make sure 
                that you select the same mouse device in the setup program 
                of your application as the mouse mode (Microsoft Mouse or 
                Mouse Systems Mouse) of the driver.
