Commands for typematic rate not working

May 21, 2017 at 09:07:00
Specs: Linux x86_64
I'm using DOS 6.20. In my autoexec.bat I've got

MODE CON RATE=32 DELAY=2

This should give me a faster cursor than the default. But it doesn't seem to make any difference. Whatever figures I specify in the command, the result is the same. Why isn't it working?

Some keyboards do not recognize this command.

MS-DOS Works With BIOS, And Uses BIOS Interrupt (INT 16h).
Set Typematic Rate in BIOS, Also.

Good Luck.

It doesn't speed up the cursor, but the repeat speed and related delay, as specified in TechDOS' link

rate= r : Specifies the rate at which a character is repeated on the screen when you hold down a key.
delay= d : Specifies the amount of time that must elapse, after you press and hold down a key, before the character output starts to repeat

Thanks to all responders. I also have a little app dating from way back that does the same thing using int 16h, so going directly to the interrupt with assembly language. But that doesn't work either. Must be modern keyboards.
