I've seen Problemes with non 8n1 communications and I've also seen
problems because most USB adapters only deliver 5.5V to the lines.
I never noticed any select/poll problems and I don't think we have any
because this is handled in common code at tty level.
If you have any condition that shows something different please let
us know.
