Finally, I’ve omitted discussion of the OE pin. It can be left unconnected

during normal use; however, if for some reason it becomes useful to

disconnect the TX and RX pins on the SmartBasic from the client board,

that pin can be asserted HIGH, which will put the client-side pins on the

multiplexer into a high-impedance mode.
