Interrupt Flag (-I); Extract Flag (-X); Help Flag (-H); Updating Flags - Elo TouchSystems software Driver Manual

Interrupt Flag (-i)

The -i flag allows you to specify the software interrupt of ELODEV:
TCHBACK -i<n>
where <n> is specified in hex. This flag is necessary if more than one copy of
ELODEV is loaded, as when controlling two touchscreens. You will also need it
if ELODEV is installed at a software interrupt other than 60 through 66 (hex). If
the -i flag is not specified, the first ELODEV found when checking interrupts 60-
66 will be used.

Extract Flag (-x)

Use the -x flag to extract TouchBack from memory if it is no longer needed:
TCHBACK -x
If an error message indicates it cannot be extracted, a TSR loaded after
TCHBACK.EXE may be interfering with its extraction. Generally you should
extract TSR's in the reverse order from which they were loaded.

Help Flag (-h)

At any time, type:
TCHBACK -h
to display quick reference information on all flags and the current version of
TouchBack.

Updating Flags

You may re-run TouchBack to update the -c flag of an installed copy.
