Some more responses after my first summary of my original question:

>this morning I noticed that my server was in boot prom mode, after
>my VT100 console had stopped working, just as if I had sent a BREAK.
>Is there some way to configure the serial connection to
>prevent this ?

From: Kevin Sheehan {Consulting Poster Child}

It's actually a break that does it...

..and there is actually a way. Break is sensed by the zs (serial)
driver and
calls prom_enter, prom_enter_mon, or debug_enter or somesuch depending
on release. You can patch the driver to NOP out that call. Depends on
your adb skills and ability to find the call in zsa_??int routines.

Terminal server or serial connection from another machine is usually the

answer. I think there was even a "Consulting Special" that just didn't
sense break, don't know if it still even exists, and would recommend
doing
it another way anyway.

From: Arthur Darren Dunham

Umm, did no one mention that the 'kbd' program (and accompaning
'/etc/default/kbd' file) can manage this under Sol 2.6. Now, you
won't be able to halt the machine if you need to, but it won't go down
if the terminal is power cycled.
