Calibration

To calibrate the touch panel, run the gunzets_calib script, under X. It has been tested with both XFree86 version 3.3.6 and version 4.0. To calibrate pass the device name on the command line of the program:

gunzets_calib /dev/ttyS0	(serial device)
gunzets_calib /dev/psaux	(PS/2 device)
gunzets_calib /dev/gunzets	(USB device)

The program needs to find gunzets_control in the command search path (it uses the control program to turn off the touchscreen in X, so the calibrator can read input data).

In order to calibrate you'll need to move the mouse pointer first. You can do that with the warp command (see below) if no other pointer is available on the system. While I could use the touch panel to this aim, and delay turning it off, I didn't think of it and don't want to re-test it all. The next release will be better in this respect (too).
