I've seen this as well with the CP1400 (not the CP1500). I think it is improper OBP initialization of the ports, but I can't recall what led me to that conclusion.
With the CP1400, interestingly enough, I believe I can send an initial break if the serial console is on another Sun box but not a PC (regardless of the OS).
