4.3 The Commands in Detail
IMPORTANT NOTE ABOUT ADDRESSES IN COMMANDS
Sections 4.3.1
through
4.3.9
discuss the commands that manipulate
station controls and displays. These commands share the common
format, “[Ctrl] [function key] station_address [Enter] (station_address_2
[Enter]),” where each “station_address” is the address of the station or
CPU for which the command is intended. The station address can be
designated with any of several different keystrokes or sets of
keystrokes:
• A one- to three-digit number (required for any station with an
address greater than 10)—as always, use the numeral keys from the
top of the keyboard, not from the numeric keypad;
• [F1] through [F10] for stations 1 through 10 respectively;
• [F11] for the instructor’s station (“Me”); or
• [F12] for all students’ stations (“All”).

TATION
The View Station command is used to observe a student’s screen. Issue the
command by pressing and releasing the left [Ctrl] key, pressing the [F1] key,
designating a station address (CPU number; see the Note above), and pressing
[Enter]. While you are in View mode, the System Control Module will discard all
non-command data coming from your keyboard and mouse.
Issuing the View Station command with a station address of All ([F12]) will turn
scan mode ON. Issuing the View Station command with a station address of Me
([F11]) will restore you (the instructor) to a normal connection with your own CPU.
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.
[CTRL] I
Identify ROM
Causes the ServSwitch 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 4.3.25
).
[CTRL] N
Send Null Byte
Resets and enables the keyboard and mouse.
Issue this command to correct your keyboard or
mouse if one of them malfunctions or gets stuck.
