1.3.0.3
HOTDISP allows the user to switch displays on the fly. HOTDISP is a TSR program, therefore it
can be used while running another program. To switch display, use the hotkey sequence dis-
played when HOTDISP is loaded. Press the keys in the sequence indicated and release them
simultaneously. Pressing the LCD/CRT Hot Key Sequence (default is F9) will switch among CRT
display, LCD panel and DoubleScan mode.

HOTDISP will install in the primary copy of the DOS command shell only. HOTDISP will not install from
menu or shell programs.
This utility requires the Seiko Epson video BIOS and Extensions.
Rather than keeping a separate data file to store Hot Key Sequence, HOTDISP modifies the HOTDISP.EXE
file on disk. For this reason some virus scanners (i.e. those that maintain checksums or CRCs) may warn of
possible virus infection in HOTDISP.EXE. This will only occur after a change to the hotkey sequence.
HOTDISP may not always be able to remove itself from resident memory if other TSRs or Device Drivers are
installed after it.
HOTDISP occupies 2K of memory.
