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.
