MODE (Set Typematic Rate)

Sets the keyboard typematic rate, the rate at which MS-DOS repeats a        
character when you hold down the key for that character.

The typematic rate has two components, the rate and the delay. Some
keyboards do not recognize this command.

Syntax

    MODE CON[:] [RATE=r DELAY=d]

Parameters

CON[:]
    Refers to the keyboard.

RATE=r
    Specifies the rate at which a character is repeated on the screen when
    you hold down a key. Valid values are in the range 1 through 32. These
    values are equal to approximately 2 to 30 characters per second,
    respectively. The default value is 20 for IBM AT-compatible keyboards
    and 21 for IBM PS/2-compatible keyboards. If you set the rate, you must
    also set the delay. for IBM PS/2-compatible keyboards. If you set the
    rate, you must also set the delay.

DELAY=d
    Specifies the amount of time that must elapse--after you press and hold
    down a key--before MS-DOS starts to repeat the character. Valid values
    for d are 1, 2, 3, and 4 (representing 0.25, 0.50, 0.75, and 1 second,
    respectively). The default value is 2. If you set the delay, you must
    also set the rate.
