1. setup xfree driver
   a. decompress xfhiddrv_drv.tar.gz
      #gzip -d xfhiddrv_drv.tar.gz
      #tar xvf xfhiddrv_drv.tar 
   b. Copy xfhiddrv_drv.so to /usr/lib/xorg/modules/input/xfhiddrv_drv.so 

      #cp   xfhiddrv_drv.o /usr/lib/xorg/modules/input/xfhiddrv_drv.so
   c. Add the following lines into xorg.conf(maybe in /etc or /etc/X11)file.
      If your system will not have a mouse, then use "CorePointer" instead of
      "SendCoreEvents" in the "ServerLayout" section.  Set "ServerLayout"  section
      as the following.

    	InputDevice 	"HID TOUCH" 


   d. Add the a new "InputDevice" Section as the following.

Section "InputDevice"
        Identifier  "HID TOUCH"
        Driver      "xfhiddrv"
        Option      "Device" "/dev/usb/hiddev0"
        Option      "ScreenNo" "0"
        Option      "Rotation" "0"
        Option      "SwapY" "0"
        Option      "DebugLevel" "0"
        Option      "AlwaysCore"
        Option      "UpSound" "1"
        Option      "DownSound" "1"
        Option      "AutoRightClick" "1"
        Option      "TouchMode" "2"
EndSection

RS232:
Section "InputDevice"
        Identifier  "HID TOUCH"
        Driver      "xfhiddrv"
        Option      "Device" "/dev/ttyS0"
        Option      "ScreenNo" "0"
        Option      "Rotation" "0"
        Option      "SwapY" "0"
        Option      "DebugLevel" "0"
        Option      "AlwaysCore"
        Option      "UpSound" "1"
        Option      "DownSound" "1"
        Option      "AutoRightClick" "1"

EndSection

    In the item of "Device", you must depend on your computer. So, it can be the value, 
such as the followings.
        "/dev/hiddevx"  x=0,1,..2, n
        "/dev/ttySx" x=0,1,2,..n for RS232 Device

   e. Press Ctrl+Alt+Backspace to restart X server. 

2. Setup and run Linear Utility:
   I. Linearity Utility:
   a. installation 
      step 1. decompress LinearAp.tar.gz 
         #gzip -d LinearAp.tar.gz
         #tar xvf LinearAp.tar.gz 
      step 2. copy linearity utility to /usr/local/bin
         #cp ./LinearAp /usr/local/bin
   b. Run linearity utility
      I. HID device in root terminal
      #./LinearAp  /dev/hiddevx n
      II. RS232 device in root terminal
      #./LinearAp  /dev/ttySx n
      where x=0,1,2...n, n = 4 or 9 <default>
