Well I still haven't gotten as much as a response. I'm assuming that it can't do 38,400.

Here's a better substitute.

The good news is that these work real nicely, and appear to do much more. Any baud rate. They even have a real fast rate. And have been tested to 350 feet. And also can act as a master or slave.

Sparkfun also has pretty good support, and a lot of great parts available. I ordered a boat load of stuff from them.
