Prior art alert!

in sparc64/dev/pcons.c, we recently added:

----------------------------
revision 1.3
date: 2000/07/10 20:24:23;  author: eeh;  state: Exp;  lines: +23 -5
Break into debugger by typing `+++++',
----------------------------

It seems to me that both are the right idea; the character should be configurable
in an MI fashion, but requiring more than one of them seems to be reasonable,
given the inavailability of ltos of extra characters.

But more importantly, we should do it in a single consistent way.

Reasonable?

Also, I think this is a substantial enough feature that it deserves a CHANGES
entry.

| 
| Log Message:
| Add options DDB_BREAK_CHAR.  This overrides break on the serial console
| break character with the supplied one.  This is useful for cases where
| break is hard to generate, or you are connected to a PC that "sends"
| breaks when power cycled.  For this mode in com, interpret break char
| in the polling section, which allows entry into the debugger before
| the tty is opened.  Only supported in the com driver currently.
