   This driver is a re-write from the MuTouch driver provided in XFree86.
   Extended options in the MuTouch firmware are not used as it wasn't
   an issue during the writing of this driver.
   Baudrate has also been rewritting to automatically adjust to 19200 if
   its support else it uses 9600.

   Feel free to change according to your needs, but changing both
   MuT_MINX as well as MuT_MINY is required to adjust the orientation
   of the touchscreen. We've had numerous occasions where the one
   touchscreen was installed in a different orientation than others.
   Also don't forget to adjust the MuT_SCREENWIDTH and MuT_SCREENHEIGHT
   for the appropriate screen dimension.

   Not much time has been spent writing this driver therefore expect errors.
   Calibration process has also been omitted since there are applications
   to do the calibration process.

   Lastly, please don't email me regarding technical informations. I
   don't work for 3M. But if you have any new ideas on improving this
   driver, please don't hesitate to share it with me.

 * Jacques Luder j.luder@laposte.net
 * Baudrate adjust now realy working !
 * version 0.3 10/09/2006 Jacques Luder j.luder@laposte.net
