I got my hardware working again. If others are attempting the same thing, make sure you note that the MAX233 needs to have the internal capacitors wired differently than the MAX233A.
I am still getting the same issue with bus initialization. I don't get an OK or FAILED. I just get the prompt character again and then it repeats on the next command.
dcb, could you post the code that you used or message it to me.
