Does the RED state exception trigger if you manually break to the prom

It seems I can not break from running kernel to PROM by sending break
from minicom. PROM itself reacts to my break (during memory test for
example) so it's Linux not accepting the break. I seem to remember it
having worked some time ago, although not when the kergel hung.
Argghh.
There were some changes to sunsab.c a couple of versions ago; maybe we
broke it.
Can you confirm BRKs are being received with
'sudo cat /proc/tty/driver/serial'
?
Relooking over sunsab.c, the BRK stats will only be accumulated if
sent with data, which may not be the case here.
Maybe check that '/proc/sys/kernel/stop-a' is set to 1.
For that matter, what is '/proc/sys/kernel/reboot-cmd'?
