Description
Locks the console keyboard. This is a software
function which prevents entry of restricted commands
(refer to UNLOCK command for list of restricted
commands). All other DSD commands can be enter-ed
when the console is locked. The console is normally
locked when the system is being used in a production
environment.
This command is used to change the current system
date. The console must be unlocked before entry of
this command is permitted (refer to UNLOCK command).

This command is used to change the current system
time. The console must be unlocked before entry of
this command is permitted (refer to UNLOCK command).

Reverses the current set or clear condition of debug
mode. When debug mode is set, the message DEBUG
appears in the header of the left screen display. Debug
mode provides system origin privileges to validated
users and allows modifications to be made to the
running system. The console must be unlocked before
entry of this command is permitted (refer to UNLOCK
command). In addition, use of debug mode is not
commonly allowed in normal production environment.
Reverses current setting of engineering mode. When
engineering mode is set, the message ENGH appears in
the header of the left screen display. Engineeringmode
allows PPU /hardware diagnostics and FOHMAT /FDP to
be executed. The console must be unlocked before entry
of this command is permitted (refer to UNLOCK command).
This command sets monitor in step mode. When step mode
is set, the message STEP appears in the header of the left
screen display. Setting monitor in step mode stops all
central memory I/O operations and prevents the system
from processing PPU requests when the next monitor
function is encountered. Pressing the space bar releases
the present step and stops again for each subsequent
monitor function. The console must be unlocked before
entry of this command is permitted (refer to UNLOCK
command). In addition, this command is generally used
by the site analyst for debugging purposes and should not
be used in a normal production environment. The operator
should enter this command only when preparing for a
level 3 recovery deadstart (refer to section 2).
