     tpctl -- touch panel calibration utility

     tpctl [-hnuv] [-D dispdevname] [-d devname] [-f filename]

     tpctl is a touch panel calibration utility.  tpctl calibrates a touch
     panel and saves and restores the calibration parameters into/from a
     parameter database file.

     Available command-line flags are:
     -D dispdevname   Specify display device name.
     -d devname       Specify touch panel device name.
     -f filename      Specify alternate parameter database file name.
     -h               Print brief description.
     -n               Do not change the parameter database file.
     -u               Force calibration.  Without this flag, tpctl won't do
                      calibration if the database file already contains param-
                      eters for the touch panel.
     -v               Verbose mode.

     You calibrate the touch panel the first time you run tpctl.  If you see a
     cross cursor on the screen, you should tap the center of the cursor to
     calibrate the touch panel, or you can abort the calibration with the
     `ESC' key.  Five cursors will appear on the screen in turn.  Once cali-
     bration is done, tpctl saves the calibration parameters into the database
     file and uses the saved parameters to calibrate the touch panel.

     You can run tpctl automatically with /etc/rc.d/tpctl.

     /etc/tpctl.dat  The default calibration parameter database file.  The -f
                     flag may be used to specify an alternate database file
                     name.  tpctl will create an empty database file if it
                     doesn't exist.
     /dev/ttyE0      The default display device, which is used to display the
                     cursor during calibration.  The -D flag may be used to
                     specify an alternate display device name.  The display
                     device must provide the `hpcfb' interface as defined in
     /dev/wsmux0     The default touch panel device.  The -d flag may be used
                     to specify an alternate touch panel device name.


     tpctl isn't available on all ports because it requires a display device
     which provides the `hpcfb' interface.
