That's on OS command I believe? I could be wrong, but the man command
implies this. I have used it to set framebuffer modes (on a SS10) in
the OB from inside Solaris IIRC.
My Netra doesn't even get that far by a long way - there's no OS
installed and even if it were I never have my OpenBoot/Firmware
machines set to auto-boot (with the exception of Macs - they make it a
bit harder to do than your average Sun/IBM/HP). When I say jump, they
jump. Trouble is someone stole my loudhailer for this machine ;)
That's why I specifically asked for a LOM or hardware method.
You'd have thought that on a headless server Sun would have made sure
you couldn't kill the console, and if you could there was an easy-ish
way to get it back :P
