 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)
  	...
