Looks okay to me. What's the glaring error on the diagram? I've not used the 233 much but from what I remember, the example circuit is pretty much what you use.

Shoot, that's what I was afraid of. It looked good to me, too..
(The error is the fact that the chip is labeled as having 3 outputs, and only one input.)

Me.
