It's been a long time since I used slowlaris, but I'm sure there was a config setting to stop this, I just can't remember where it was :)

I'm not sure that's really a bug (at least not on Sun's part).
Sending a break *should* drop you to the PROM. Certain terminals were buggy, in that they sent a break when power cycled or in some cases, as they were being disconnected. In particular, Cisco's terminal servers had this fault. Hilarity ensued at a previous employer when 16 live servers connected to an AS2511-RJ all went down simultaneously. Not. We ditched Cisco terminal servers very soon afterwards, and switched to Cyclades instead, which were generally much better all round.

Like Richard, I hate the fact that PCs don't have proper serial consoles. The vendor recommended solution always seems to be KVM over IP instead, which anyone that's tried it to a datacentre in the Far East will know simply isn't a viable alternative. Plus it doesn't work from my mobile phone. A serial console does. Which means I can be out and about when on call, rather than tied to my desktop or having to lug a laptop around.
