Keep Settings
[Ctrl] K
Enter this command after you enter any of the four commands listed below
(It saves the new settings to nonvolatile memory):
Set Scan-Delay
Time
[Ctrl] Txx [Enter]
(xx = 1 to 15)
Sets the time, in seconds, that the ServSwitch Jr. LP will pause at each
CPU when scanning.
Set Mouse Mode
[Ctrl] Qx [Enter]
(x = 0, 1, or 2)
For the selected CPU, Q1 translates PS/2 mouse input to serial mouse
output, Q2 forces PS/2 wheel-mouse output, and Q0 resets to normal PS/2
non-wheel-mouse-output.
Set Keyboard Mode
[Ctrl] Mx [Enter]
(x = 1,2, or 3)
Tells the Jr. LP the keyboard mode (1, 2, or 3) of the currently selected
CPU.
Set Keyboard
Typematic
[Ctrl] Axxx [Enter]
(xxx = decimal value
from 0 to 127; see
below)
Sets the keyboard typematic (automatic key-repeat) function of the currently
selected CPU, as described in the table below.
The keyboard typematic is an internal seven-bit value maintained by some keyboards. The last five bits control the typematic
rate (how often a held-down key repeats); the first two bits control typematic delay (how long a key must be held down before it
starts to repeat). Add the two values together to get the value of the argument for the Set Keyboard Typematic command:
