tpctl —

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-d
    devname-f
    filename-h-n-utpctl won't
      do calibration if the database file already contains parameters for the
      touch panel.-vYou 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 calibration 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.
-f flag may be used to specify an alternate
      database file name. tpctl will create an empty
      database file if it doesn't exist.-D flag may be used to specify an
      alternate display device name. The display device must provide the
      ‘hpcfb’ interface as defined in
      /usr/include/dev/hpc/hpcfbio.h.-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.
