Operating Systems Solaris Can this be disabled? interface turned of when console cable plugged in. Post 302098251 by Perderabo on Friday 1st of December 2006 01:31:47 PM

Sending a break signal on the system console causes the OS to drop into firmware mode and issue an "OK" prompt. Want the OS to start running again? Just type this command:
go

The reason is that Sun thought it would be cool if you could drop the machine to firmware mode by just unplugging and reconnecting the system console. It is possible for the OS to change this behaviour a second or two after a reboot, but there is still a very tiny window during boot where a break will work.

For solaris 2.6 get patch 105924-10 or later
For solaris 7 get patch 107589-02 or later
After solaris 7, no patch is needed.

Then modify /etc/default/kbd to have line like:
KEYBOARD_ABORT=alternate
Then after next reboot, you drop to firmware with ~^b (tilde, control-b)

There is also a kbd command to do this on the fly.
