Most IBM type keyboards have an internal seven-bit “typematic” setting, which
governs the way the keyboard responds when you hold a key down to force it
to repeat. (This command does not apply to Apple or Sun keyboards, because
the ServManager does not support the typematic function for them at this
time.) The five “low” bits of this setting represent the
rate
at which the key
repeats; the two “high” bits represent the
delay
after you begin holding down
the key before it begins to repeat.
Sometimes a keyboard’s typematic setting isn’t suitable for a given operator
or for a given application. To change the shared keyboard’s typematic setting,
issue the Set Keyboard Typematic command: Press and release the left
Control Key, type [A] followed by the desired “typematic value,” and press
[ENTER]. The “typematic value” is the decimal equivalent of the binary seven-
bit typematic setting: While the typematic setting = delay bits + rate bits, the
typematic value =
decimal
delay value +
decimal
rate value (see Table 4-6 below
and Table 4-7 on the next page). For example, to set the shared keyboard to
register a key 16 times per second after the key has been held down for half a
second (typematic value = 7 + 32 = 39), type
[CTRL] [A] [3] [9] [ENTER].
