Chapter 4 - DOS Touchscreen Driver and Calibration Utility
Updating Flags
ELODEV may be re-run to modify the settings of a previously installed copy. For
example:
ELODEV -w90
Note that no controller information is specified.
Only the -c, -s, -w, and -p flags can be changed using this method. To change the
-i flag, extract and reinstall ELODEV as explained above.
If ELODEV is installed at a software interrupt other than the default, include the -i
flag:
ELODEV -w90 -i61
You can use the INFO.EXE utility (typically in \TOUCH) to confirm the updated
settings. See page 108.
Using Multiple Co-Resident Copies of ELODEV
Multiple copies of ELODEV are useful if the application program controls
multiple touchscreens, or if the application is being tested with different
controllers and/or configurations.
Install each copy of ELODEV using a different software interrupt flag (-i<n>, see
page 31). Each copy of ELODEV must have its own calibration values. Use
ELOCALIB -i<n> to calibrate a specific copy of ELODEV. ELOCALIB will
correctly update calibration data in your AUTOEXEC.BAT file even if multiple
copies of ELODEV are loaded there.
INFO, ELODEMO, MonitorMouse for DOS, and TouchBack all support the -i
flag to specify the copy of ELODEV they should use. If you do not specify the -i
flag, the first ELODEV found while scanning interrupts 60 66 (in that order) will
be used.
