INT 96 U - KILL.COM, QKILL.COM - POP UP

by calling INT 21/AH=4Ch or reboot the computer (author unknown);
QKILL.COM is a modification of KILL.COM by Solar Designer that
supports QEMM's Quick Boot feature
Notes: This interrupt is intercepted but not chained by KILL.COM; it is never
called by KILL.COM itself. It points into the middle of KILL.COM's
INT 09 handler and assumes specific values have been placed on the
stack (thus it can't be called as an interrupt).
To invoke KILL, use the following code:
pushf
push cs
push offset $+0Dh
push ax
push es
push 0
pop es
jmp dword ptr es:[96h*4]

--------S-FD---------------------------------
INT FD - TFPCX - INSTALLATION CHECK
AH = function (also see separate entries below)
Program: TFPCX is an interface between modem and terminal program for packet-
radio communications
Notes: the installation check consists of testing for the string "N5NX" three
bytes beyond the interrupt handler; INT FD is the default, but may
be changed, so the full installation check consists of scanning
for the signature
TFPCX returns AX=FFFFh on any unsupported function call
SeeAlso: AH=01h,AH=03h,AH=FEh
--------S-FD01-------------------------------
INT FD - TFPCX - TEST FOR CHARACTER WAITING
AH = 01h
Return: AX = status
0000h no characters waiting
0001h character available for input
Program: TFPCX is an interface between modem and terminal program for packet-
radio communications
SeeAlso: AH=02h
--------S-FD02-------------------------------
INT FD - TFPCX - GET CHARACTER
AH = 02h
Return: AL = character
Notes: this call is only allowed if AH=01h indicated that a character is
available
all available characters should be read before sending any additional
characters
SeeAlso: AH=01h,AH=03h
--------S-FD03-------------------------------
INT FD - TFPCX - OUTPUT CHARACTER
AH = 03h
AL = character to send

Program: TFPCX is an interface between modem and terminal program for packet-
radio communications
SeeAlso: AH=01h,AH=03h
--------B-FE---------------------------------
INT FE - AT/XT286/PS50+ - destroyed by return from protected mode
Note: the ROM BIOS uses 0030h:0100h as the initial stack on startup, which
is the last fourth of the interrupt vector table. If the processor
is returned to real mode via a hardware reset (the only possibility
on an 80286, though there are a number of ways of generating one),
then the BIOS startup code stacks three words on its scratch stack
before determining that a return to real mode has been requested.
As a result, INT FE and INT FF are corrupted.
SeeAlso: INT FF"XT286"
--------T-FE---------------------------------
INT FE - DoubleDOS - GIVE UP TIME
AL = number of 55ms time slices to give away
Return: after other program (if active) has run
