INT 14 - MultiDOS Plus - SET MONITOR MODE AH = 24h AL = port status storage 00h single status for entire receive buffer 01h separate status kept for each byte in receive buffer DX = port number Return: AH = status 00h successful 3Ah invalid status storage specified 41h no such port 64h monitor mode already active Note: in monitor mode, MultiDOS redirects all BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. video output to a serial port SeeAlso: AH=20h"MultiDOS",AH=25h
