Probably because the first stty opens the port, applies the option,
and then closes it. And when it closes, its settings go back to
default. The trick I've seen used is
sleep 100000 </dev/tty00 & # keep port opened for a long time
stty -f /dev/tty00 <blah> # set option <blah>
stty -a -f /dev/tty00 # shows changed <blah>
