5.2.7 Emulated Features
Keyboard: INT 16 command interrupt
AH = 0: read key from keyboard buffer
AH = 1: check if keyboard buffer is empty
AH = 2: report keyboard status bits
AH = 10h: see AH = 0
AH = 11h: see AH = 1
Video: INT 10 command interrupt
Remote video console supports only mode 3: text mode 80*25. In this mode it works like a twin of the main
display, which is always enabled.
AH = 0, AL=3: only, all other modes will be ignored on the remote console
AH = 2:
set cursor position (display page = 0)
AH = 6: scroll up
AH = 7: scroll down
AH =9: write "char" and attribute
AH = 0Ah: write "char" and attribute
AH = 0Eh: write "char" teletype
AH = 13h: write text string (emulated over AH = 2 and AH = 0Eh commands)
Note: Remote "emulator" does not support direct access to the screen memory. Popular software, such as Norton
Commander, will not work properly with remote video console, and the picture will be visible only on the
remote computer screen.
Floppy Disk: INT 13
When the remote floppy disk is enabled, all floppy disk requests will be redirected to the remote console
application; all requests to the hard disk will be executed by the native BIOS.
To make the "remote floppy disk" bootable, it is necessary to make a floppy image from a bootable floppy disk.
