Just FYI, you should be able to send BREAK from within qemu.  From the
qemu man page:

	...
	During emulation, if you are using a character backend
	multiplexer (which is the default if you are using -nographic)
	then several commands are available via an escape sequence.
	These key sequences all start with an escape character, which
	is Ctrl-a by default, but can be changed with -echr. The list
	below assumes you're using the default.
	...
	Ctrl-a b
	    Send break (magic sysrq in Linux)
	...
