4.3 Preparations for Use
4.3.7 How to enable/disable the break signal
CAUTION
Data Destruction
If improper commands are used at the ok prompt, data may be lost. If you need
to use any command except those shown in this manual, you should fully
understand the function and usage of the command before using it.
Data is sometimes lost as the bootup sequence shifts to display of the ok prompt during system operation in
response to a break signal from the console terminal connected to the serial port or the STOP+A command from
the keyboard.
To prevent this kind of response to a break signal arriving from the serial port or the STOP+A command from the
keyboard, make the following settings using the set-fw-options command shown below with the ok prompt
displayed on screen, and then set the MODE switch on the control panel to the SECURE mode.
How to disable the break signal and STOP+A command
1
Use the print-fw-options command to check the current setting.
The factory default is that nothing is set.
ok
print-fw-options
fw-options =
2
Use the set-fw-options command to set the value (no-break) for disabling the break signal and
STOP command.
ok
set-fw-options no-break
fw-options = no-break
3
Use the print-fw-options command to make sure that no-break is correctly set.
ok
print-fw-options
fw-options = no-break
