-f is not -F
When the tty is closed, it reverts to the default configuration.
There is no support for this -F method.
What you need to instead is wrap all this in a way which keeps the
tty open
(
stty 9600 sane parenb -parodd crtscts cs7 igncr
do your IO loop
) </dev/ttyU0 0>&1 0>&2
Something like that.
