Summary:
Serial line noise seems to be a product of certain pieces of hardware. In
my case I was using a wintel box (Hyperterminal) and connected to my
servers with a DB9 connector and x-link 10b/t cable to the serial
management port on my Sun box over time noise started to emanate and this
noise began to hit upon a keyboard interrupt sequence that is not a bug but
a function of debugging per Casper Dik (who responded first with the edit
/etc/default/kbd suggestion) below.
Lastly, many suggested ensuring the hardware key is set to "locked" as well.

"What you're witnessing is the return to OBP upon receipt of a break
signal; this is a tremendously useful feature when debugging problems;
of course not when it happens by accident.
It's not a bug, it's a feature.
You can configure Solaris not to exit to OBP using "kbd -a alternate"
which switches to the alternate sequence.
In order to make this change persistance across reboots, edit
/etc/default/kbd."
