Well... not entirely. If you have a line answer at 1200, it will take a
break to get it to 2400 (or higher). However, if the line is at a higher
speed, say answers at 2400 and you want 1200, a RETURN will generate a
framing error, which is how BREAK is detected, and cause the speed to
shift.

Because (a) this is more intuitive for humans, and (b) some old version
of SCO don't seem to send real breaks, I went with high speed first on
all of the systems I operate.

Like all hardware characteristc, this may vary, and you may get an
upshift on RETURN just fine.
