Drawbot USB to RS-485 converter up and running

I found out soldering .025 pitch leads is pretty tough.  I let the magic smoke out of one FTDI chip before I really figured out how to do it.  This evening I found the last bugs, and now it's up and running.  Using the frequency counter feature of my meter I can tell the output changes when I send in data over USB, but I don't have any RS-485 devices right now to check if the data is any good.  I guess that's the next task before I send the boards out for fab.
