well "break" is used a couple of different ways, but they all come
down to this, if the serial port does not transfer a character at
the specified baud rate for the 8/7 bits of time it takes, then
there is a break set in the serial driver(atleast if you are using u8250).
So breaks are all to easy to send, just dont put anything out through
the port for a given amount of time - 500 mSec is fine - so is 2 seconds.
I like the book "C programmers guide to serial communications" of its 600+
pages it devotes about 2 pgs to break, which isn't indexed either.
