Command: nansi.sys
NANSI.SYS is a console enhancing driver. FreeDOS uses NANSI.SYS
instead of ANSI.SYS.
NANSI.SYS has to be loaded in CONFIG.SYS / FDCONFIG.SYS.
When FreeDOS is already running, you can load NANSI.SYS later
with DEVLOAD.
Syntax:
DEVICE[HIGH]=[drive:][path]NANSI.SYS [/K] [/C] [/X] [/S] [/Tnn] [/R]
[/B|/Q] [/P]
DEVLOAD [drive:][path]NANSI.SYS [/K] [/C] [/X] [/S] [/Tnn] [/R]
[/B|/Q] [/P]
Options:
/K Force 84 key keyboard style.
/X Extended key definitions.
/S Safe mode - no key redefinitions.
/Tnn Mode nn is a text mode.
/R Use BIOS (for some screen readers).
/B Use BIOS for bell sound.
/Q Use no bell sound at all (quiet).
/P Pass all unknown requests to CON.
/C Force 101+ key keyboard style.
/? Shows the help.
Comments:
When loaded (for more information please read nansi.doc):
ESC[#;#H Cursor Position specified by parameters.
ESC[#;#f Horizontal and Vertical Position.
ESC[#A Cursor Up.
ESC[#B Cursor Down.
ESC[#C Cursor Forward.
ESC[#D Cursor Backward.
ESC[#n Device Status, Report! # must be 6. The sequence
ESC[6n causes the console driver to output Cursor
Position Report.
ESC[#;#R Cursor Position Report.
ESC[s Save Cursor Position.
ESC[u Restore Cursor Position.
ESC[#J Erase in Display.# must be 2. Clears the entire
screen.
ESC[K Erase in Line. Deletes from the cursor to the end
of the line.
ESC[#L Insert Lines - not supported in ANSI.SYS.
ESC[#M Delete Lines - not supported in ANSI.SYS.
ESC[#@ Insert Characters - not supported in ANSI.SYS.
ESC[#P Delete Characters - not supported in ANSI.SYS.
ESC["string"p Keyboard Key Reassignment. This feature is a
security risk, and can be disabled with the /s
option when loading NANSI.SYS in config.sys.
