My company has a Plexus P40 (Z8000 System III) box,
and the way I fixed this problem was to find an empty port,
open it CLOCAL at 300 baud, and write a bunch of characters to it
before sending the second carriage return. A real hack, but it
does work for those individuals who don't have a timer resolution
better than 1 second.
