CONFIGURATION DETAILS

       Please  refer to xorg.conf(5) for general configuration details and for
       options that can be used with all input  drivers.   This  section  only
       covers  configuration  details  specific  to  this  driver.  For better
       understanding please read also the CTS manual and various  IRT  manuals
       which  are available in "pdf" format from Citron web page www.citron.de
       or directly from Citron.

       The following driver Options are supported:

       Option "Device" "devpath"
              Specify the device path for the  citron  touch.   Valid  devices
              are:

                   /dev/ttyS0, /dev/ttyS1, ....

              This  option  is mandatory.  It's important to specify the right
              device Note: com1 -> /dev/ttyS0, com2 -> /dev/ttyS1 ....

       Option "ScreenNumber" "screennumber"
              sets the screennumber for the citron InputDevice.

              Default: ScreenNumber: "0"

       Option "MinX, MinY" "value"
              These are the minimum X  and  Y  values  for  the  citron  input
              device.

              Note: MinX, MinY must be less than MaxX, MaxY.

              Range: "0" - "65535"

              Default: MinX: "0"  MinY: "0"

       Option "MaxX, MaxY" "value"
              These  are  the  maximum  X  and  Y  values for the citron input
              device.

              Note: MaxX, MaxY must be greater than MinX, MinY.

              Range: "0" - "65535"

              Default: MaxX: "65535"  MaxY: "65535"

       Option "ButtonNumber" "value"
              This value is responsible for the button number that is returned
              within the xf86PostButton event message

              Range: "0" - "255"

              Default: "1"

       Option "ButtonThreshold" "value"
              This  value is responsible for the button threshold.  It changes
              the pressure sensitivity of the touch. A  higher  number  corre-
              sponds to a higher pressure.

              Note:  This  feature  is  only available with pressure sensitive
              hardware.

              Range: "0" - "255"

              Default: "20"

       Sleep-Mode
              If the IRT is in Doze-Mode and Touch Zone is not interrupted for
              another   certain   span   of   time,  the  so-called  Slee-Mode
              is activated. The Sleep-Mode decreases  the  scan  rate  of  the
              beams even further than the Doze-Mode does (see below). This way
              the life expectancy of the beams is prolonged and the power con-
              sumption  of  the IRT is reduced.  As soon as an interruption of
              the Touch Zone is detected, the Sleep-Mode  is  deactivated  and
              the  Touch  Zone  will  again be scanned with the maximum speed.
              With the Sleep-Mode activated, depending on the  set  scan  rate
              the  IRT's response time can be considerably longer as in normal
              operation. If, for example, a scan rate of 500 ms / scan is set,
              it  may  last up to a half of a second until the IRT detects the
              interruption and deactivates the Sleep-Mode.

       Option "SleepMode" "mode"
              This value is responsible for the sleep-mode of the touch.
              Determines the behaviour of the Sleep-Mode.

              0x00
               No message at either activation or deactivation

              0x01
               Message at activation

              0x02
               Message at deactivation

              0x03
               Message at activation and deactivation

              0x10 GP_OUT output set according to the Sleep-Mode status

              Values: "0" "1" "2" "3" "16"

              Default: "0"

       Option "SleepTime" "time"
              This value is responsible for the sleep-time of the touch. It is
              the  activation  time  in  seconds ("0" = immediately activated,
              "65535" = always deactivated).

              Range: "0" - "65535" [s]

              Default: "65535" => deactivated

       Option "SleepScan" "scan"
              This value is responsible for the scan-time of the  touch.  This
              is  the  time  interval  between  two  scan  operations while in
              Sleep-Mode. The time interval is set in steps of milliseconds.

              Range: "0" - "65535" [ms]

              Default: "500"

       Option "PWMAdjSrc" "value"

       Option "PWMAdjDst" "value"
              These parameters are used to adjust the brightness of  different
              backlight  inverters.  At  the  moment 2 backlight inverters are
              used: 0=TDK  1=AC. If you want a AC backlight inverter to behave
              like  an AC type you have to set PWMAdjSrc to 0 (TDK) and PWMAd-
              jDst to 1 (AC).

              Range: "0" - "1"

              Default: "-1" (no adjustment)

       Option "PWMActive" "value"
              This value determines the mark-to-space ratio of the PWM  output
              while  in normal operation (sleep-mode not active).  Higher val-
              ues result in longer pulse widths. This  output  signal  can  be
              used in conjunction with the Citron AWBI to do backlight-dimming
              via the touch.

              Range: "0" - "255"

              Default: "255" (max. brightness)

       Option "PWMSleep" "value"
              This value determines the mark-to-space ratio of the PWM  output
              while in sleep-mode (-> SleepMode, SleepScan, SleepTime ) opera-
              tion (sleep-mode active).  Higher values result in longer  pulse
              widths.

              Range: "0" - "255"

              Default: "255" (max. brightness)

       Option "PWMFreq" "value"
              This value determines the PWM frequency in Hertz

              Range: "39" - "9803"

              Default: "9803" (max. frequency)

       Option "ClickMode" "mode"
              With mode one can select between 5 ClickModes

              "1" = ClickMode Enter

              With  this  mode  every  interruption of the infrared beams will
              activate a ButtonPress event and after the interruption  a  But-
              tonRelease event will be sent.

              "2" = ClickMode Dual

              With  this  mode  every interruption will sent a Proximity event
              and every second interruption  a  ButtonPress  event.  With  the
              release  of  the  interruption  (while one interruption is still
              active) a ButtonRelease event will be sent.

              "3" = ClickMode Dual Exit

              With this mode every interruption will sent a ProximityIn  event
              and  every  second  interruption  a  ButtonPress event. With the
              release of the interruption (while  one  interruption  is  still
              active)  no ButtonRelease event will be sent. Only if all inter-
              ruptions are released a ButtonRelease followed by a ProximityOut
              event will be sent.

              "4" = ClickMode ZPress

              With this mode every interruption will sent a ProximityIn event.
              Only if a certain pressure is exceeded a ButtonPress event  will
              occur.  If  the pressure falls below a certain limit a ButtonRe-
              lease event will  be  sent.   After  also  the  interruption  is
              released a ProximityOut event is generated.

              "5" = ClickMode ZPress Exit

              This mode is similar to "Clickmode Dual Exit".  The first inter-
              ruption of the beams will sent a ProximityIn event.  Only  if  a
              certain  pressure is exceeded a ButtonPress event will occur. If
              the pressure falls below a certain limit no ButtonRelease  event
              will be sent.  After the interruption is also released a Button-
              Release followed by a ProximityOut event is generated.

              Range: "1" - "5"

              Default: "1" (ClickMode Enter)

       Option "Origin" "value"
              This value sets the coordinates origin to one of the  four  cor-
              ners  of  the  screen.   The  following values are accepted: "0"
              TOPLEFT: Origin set to  the  left-hand  side  top  corner.   "1"
              TOPRIGHT:  Origin  set  to  the right-hand side top corner.  "2"
              BOTTOMRIGHT: Origin set to the right-hand  side  bottom  corner.
              "3" BOTTOMLEFT: Origin set to the left-hand side bottom corner.

              Range: "0" - "3"

              Default: "0" (TOPLEFT)

       Doze-Mode
              If for a certain span of time the Touch Zone is not interrupted,
              the so-called Doze-Mode is automatically  activated.  The  acti-
              vated  Doze-Mode  slightly decreases the scan rate of the beams.
              This way the power consumption of the IRT is reduced. As soon as
              an  interruption of the Touch Zone is detected, the Doze-Mode is
              deactivated and the Touch Zone will again be  scanned  with  the
              maximum speed.

       Option "DozeMode" "mode"
              This value is responsible for the doze-mode of the touch.

              Determines the behaviour of the Doze-Mode.

              0x00 No message at either activation or deactivation

              0x01 Message at activation

              0x02 Message at deactivation

              0x03 Message at activation and deactivation

              0x10 GP_OUT output set according to the Doze-Mode status

              If  the GP_OUT output is already controlled by the Sleep-Mode it
              is no longer available as an output port anymore.

              Default: "500"

       Option "DeltaX" "value"
              This value determines a virtual area at the left and right  side
              of  the  current  cursor  position where the cursor didn't move.
              Within this area no "MotionNotify" event will be sent.

              Range: "0" - "255"

              Default: "0" (no deltaX)

       Option "DeltaY" " value "
              This value determines a virtual area at the top  and  bottom  of

       Option "PressVolKey" "value"
              This value determines the duration of the speaker on period when
              a "KeyPress" event is sent.  It is  calculated:  (PressVolKey  *
              PressDurKey  /  50).  If you give PressVolKey a value of 50 then
              PressDurKey is the duration in [ms].

              Range: "0" - "256"

              Default: "50"

       Option "PressPitchKey" "value"
              This value determines the pitch of the tone when a "ButtonPress"

       Option "PressDurKey" "value"
              This  value  determines  the  duration  of the tone in ms when a
              "ButtonPress" event is sent.  It is calculated:  (PressVolKey  *
              PressDurKey  /  50).  If you give PressVolKey a value of 50 then
              PressDurKey is the duration in [ms].

              Range: "0" - "65535"

              Default: "120"

       Option "ReleaseVolKey" "value"
              This value determines the duration of the  speaker  on  interval
              when   a   "KeyRelease"   event  is  sent.   It  is  calculated:
              (PressVolKey * PressDurKey / 50).  If  you  give  PressVolKey  a
              value of 50 then PressDurKey is the duration in [ms].

              Range: "0" - "255"

              Default: "50"

       Option "ReleasePitchKey" "value"
              This value determines the pitch of the tone when when a "Button-

              Range: "0" - "3000"

              Default: "3000"

       Option "ReleseDurKey" "value"
              This value determines the duration of the speaker on period when
              a  "KeyRelease" event is sent.  It is calculated: (PressVolKey *
              PressDurKey / 50).  If you give PressVolKey a value of  50  then
              PressDurKey is the duration in [ms].
