INT 20 - Minix - SEND/RECEIVE MESSAGE
	AX = process ID of other process
	BX -> message
	CX = operation (1 send, 2 receive, 3 send&receive)
Program: Minix is a Version 7 Unix-compatible operating system by Andrew
	  Tanenbaum
Note:	the message contains the system call number (numbered as in V7
	  Unix(tm)) and the call parameters

INT 20 - DOS 1+ - TERMINATE PROGRAM
	CS = PSP segment
Return: never
Notes:	(see INT 21/AH=00h)
	this function sets the program's return code (ERRORLEVEL) to 00h
SeeAlso: INT 21/AH=00h,INT 21/AH=4Ch

INT 20 - COMTROL HOSTESS i/ISA DEBUGGER - INVOKE FIRMWARE DEBUGGER
	???
Return: ???
SeeAlso: INT 21"COMTROL"

INT 20 P - Microsoft Windows - VMM - VxD SERVICES
	VxD = 0001h
Note:	the desired VxD and service number are identified by the data
	  immediately following the INT 20 instruction, as in:
		INT	20h
		DW	service number
		DW	VxD identifier
SeeAlso: INT 2F/AX=1684h"DEVICE API",INT 30"Windows",#01265,#01340
