HBREAK [/R=0|1] [/T=scan code] [/S=.shifts/] [/ML] [/U] [/?|H]
Hbreak is an utility capable of abort the execution of programs. It can
recover some .computer crashes/. The only caution is not to invoke it in the
middle of another TSR execution (vg. SideKick). It is not recomended use it
while DOS PRINT is working. HBREAK is very much powerful that Ctrl-Break and
interrupts 99% of programs (if DOS is not corrupted and INTs are enabled).
This edition of HBREAK relocates the first 8 hardware INTs from habitual
zone of 8-0Fh to new zone 50-57h: this is the only alternative location that
MS-DOS 5.0 EMM386 support. This is not conflictive with Windows 3, but /R=0
switch avoid this action (perhaps necessary on some future systems): this
option decrease the efficacy. The EMS memory assigned will be recovered (and
the XMS with QEMM386 and similar memory managers) in the most of cases.
Activation keys may be selected with /T and /S (to obtain .shifts/ value
you must add: 1-Right Shift, 2-Left Shift, 4-Ctrl and 8-Alt).
/ML switch forces installation in conventional memory (HBREAK is a upper
memory self-installable utility, with or without DOS=UMB statement in the
CONFIG.SYS). /U tells HBREAK to uninstall (if possible). HBREAK takes from
3248 to 3344 bytes of memory in most systems.
