Depending on what you're sending the break to, you may be able to get
away with setting the baud rate to something really slow (like 50 baud)
and sending a single NUL.
I've got some consoles on a serial interface that's slightly broken
when sending breaks (software issues I haven't yet had the leisure and
inclination to track down) and I've done the "speed down and send NUL"
trick on a few occasions.
