-> get gpm 1.20 from ftp://arcana.linux.it/pub/gpm and install this package
-> now kill any running gpm and do :
-> "gpm -t acecad -m /dev/ttyS0" or 
-> "gpm -t genitizer -m /dev/ttyS0"

For WizardPad do:

-> "gpm -t wp -m /dev/ttyS0" for digitizer on COM1: 
-> "gpm -t wp -m /dev/ttyS1" for digitizer on COM2:

-> this will make WizardPad work under console in absolute mode

WizardPad
Tablet works with xfree86 using the gpm repeater-mode (-Rsumma).
For this, you need a modified gpmsumma_drv.o which is available on following webpage
http://www.hof-berlin.de/tablet/xfree4.0.0/0.0.2/gpmsumma_drv.o.

Copy the file to /usr/X11R6/lib/modules/input

Configure XF86Config which is now located in directory /etc/X11/ as follows:

Section "Module"
   Load "gpmsumma"
EndSection

Section "InputDevice"
   Driver "gpmsumma"
   Identifier "Mouse[3]"
   Option "Device" "/dev/gpmdata"
   Option "Name" "WIZARD PAD (SERIAL)"
   Option "SendCoreEvents" "On"
   Option "Vendor" "GENIUS"
EndSection

Section "ServerLayout"
    InputDevice "Mouse[3]" "SendCoreEvents"
EndSection

Before the start of X you must run on console gpm -Rsumma -t wp -m /dev/ttyS
