I have no particular comments. But it sounds like these are two
orthogonal settings.

Hey, that sounds familiar.

You can't acheive this in an agent, because we're talking about serial
consoles here - there's no other way for the agent to know there's a
debugger attached.

This sounds more like "set remote interrupt-sequence break-g" and
"set remote interrupt-after-connection on".
