  GTDriver is a program to control serial graphic tablets and serial mice
  with your Amiga.  Version 1.0 of GTDriver supports the following tablets:

- Summagraphics MM
- Summagraphics Bitpadone
- CalComp 2000
- Cherry
- TekTronix 4957
- Wacom

and the following mice:

- Microsoft mouse
- Mouse System mouse

If your tablet or mouse emulates one of the previous models you can use it
with GTDriver (if not, contact the authors to have your device supported in
the next release of the package).

GTDriver has many parameters that can be configured using the prefs program
GTDOptions.  Among the parameters you find the emulation type, the baud
rate, the dpi tablet resolution, the dimensions of the clip region, etc.

GTDriver has two working modes: 'driver mode' and 'server mode'.  In
'driver mode' the pointing device of the tablet becomes a mouse
replacement, and you can use the tablet with any program.  If you have a
digitizing puck, it may have more than two buttons.  However, only three
buttons are supported in 'driver mode'.  The third button is mapped to the
third Amiga mouse button (that is supported by few programs).

'Server mode' is intended for programmers only.  You can write your own
programs that use GTDriver in server mode: in this way GTDriver will not
control the screen pointer, and will send complete tablet information to
your program in a documented format.  By using GTDriver in 'server mode'
your software can take full advantage of any tablet feature.

GTDriver supports user-defined tablet buttons (called pseudo-buttons or
p-buttons).  A p-button is a rectangular area on the tablet, to which an
arbitrary key combination has been associated.  Whenever you press the
stylus on a pseudo button, its key combination is sent to the active
program just like you were pressing it on the keyboard.  As many programs
use keyboard shortcuts to select tools and menu items, you can define sets
of p-buttons even for programs not explicitly written to work with
GTDriver.  For example, you can use Deluxe Paint or DynaCadd with a graphic
tablet without having tool bars on the screen, without selecting menu items
and, most of all, without the software being aware of GTDriver!

  - Message port with support for many commands;
  - Two working modes: 'driver mode' (mouse replacement mode) and 'server
    mode' (direct control for programmers);
  - Support for user defined pseudo-buttons on the tablet; a pseudo button
    is associated to a keyboard sequence so that button masks can be
    created to control software that isn't aware of GTDriver (Deluxe Paint,
  - Font-sensitive AUISG-compliant preferences program (GTDOptions);
  - Enforcer and Mungwall test for both GTDriver and GTDOptions;
  - Dvi, Amigaguide, ASCII and ANSI text documentation;
  - C source example to show how to program GTDriver in 'server mode';
  - Deluxe Paint 4.5 pseudo-button mask included;

  GTDriver is available for anonymous FTP on Aminet sites such as (

     GTDriver.readme      (5146 bytes)
   GTDriver needs at least Kickstart/Workbench 2.04 to run.  A fast CPU
   it's not required but the driver may have better performance with it.

GTDriver is NOT PD.  It is shareware.  The authors keep the copyright over
the whole package.

The unregistered version of GTDriver is freely (re)distributable, but none
is allowed to sell the program for more money than to cover just the costs
of copying.

In any case noone may charge more than Fred Fish claims for one of his
"Library Disks"!
