For the Bitsy driver (ie, the Ipaq) and I would assume the Assabet (and
apparently the ADS as well), the calibration is handled directly by the
driver. Some other devices that we use requires the Microwindows driver
to handle calibration - so the tpcal program writes a series of values
that the microwindows driver can use to calibrate itself (if you are
wondering how that works, check drivers/mou_harrier.c or
drivers/mou_ts.c).
But in your case, since you are using the Ipaq driver, you want to use a
calibrator that does an IOCTL call similar to this:
if (ioctl(fd, TS_SET_CAL, (void *)&new_cal) != 0).
Check the driver source code for information on how to format the
values.
