The terminal device needs to be held open, otherwise when it
closes (when stty exits) all the modes are reset back to
the default for the next open.

Ah yes--had a feeling I was forgetting something...

Something like

        (stty 9600 raw; cat) </dev/ttyU0

might work, perhaps.

Shell might get stuck on open. This should work, I think:

$ { sleep 1; stty -f /dev/ttyU0 ... ; } & cat /dev/ttyU0
