Issue this command to correct your keyboard or

 

 

mouse if one of them malfunctions or gets stuck.

 

 

 

Send Null Byte

[CTRL] N

PC CPUs with PS/2 mouse ports only: Causes

 

 

the ServSwitch Jr. MP to send a null byte to the

 

 

CPU’s PS/2 mouse port. Issue this command to

 

 

correct the current CPU if it gets “out of sync” with

 

 

the PS/2 mouse (see Section 4.3.5).

 

 

 

Identify ROM

[CTRL] I

Causes the ServSwitch to report the version of

 

 

ROM it is using. Issue this command if you are

 

 

asked to do so by a technical-support person.

nonvolatile memory):

 

 

 

Set Maximum

[CTRL] Px [ENTER]

SW628A-R2 only: Tells the ServSwitch Jr. MP the

Number of

(x = 2 or 3)

total number of ports to which devices are (or will

Ports

 

be) connected. Issue this command when you’re

 

 

only using 2 or 3 of the ports on a 4-port unit.

 

 

 

Set Scan-

[CTRL] Txx [ENTER]

Sets the time, in seconds, that the ServSwitch Jr.

Delay Time

(xx = delay in seconds

MP will pause at each port when scanning.

 

from 1 to 15)

 

 

 

 

Set Keyboard

[CTRL] Mx [ENTER]

PC CPUs only: Tells the ServSwitch Jr. MP the

Mode

(x = 1, 2, or 3)

keyboard mode of the currently selected CPU.

 

 

 

Set Keyboard

[CTRL] Axxx [ENTER]

Sets the keyboard typematic (automatic key-

Typematic

(xxx = a decimal value

repeat) function of the currently selected CPU.

 

from 0 to 127)

This command works only with CPUs that have

 

 

standard keyboards and CMOS that allows users

 

 

to program the typematic function.

 

 

 

Set Apple

[CTRL] Ex [ENTER]

Determines how your PC-keyboard keys are

Emulation

(x = 0, 1, or 2)

mapped to Apple keyboard keys and functions.

 

 

 

Set Mouse
