FYI. The RCX normally runs at 2400 baud, but it is effectively 1200 baud
because the protocol sends every byte twice. Markus and I were able to get
downloads to run at a true 4800 baud by downloading a short program to hack
some registers and turn off the duplicate bytes in the protocol. We tried
9600 baud but it was very unreliable. 4800 baud was sometimes finicky, but
then so was the original 2400/2, so we stuck with 4800. Max is 4800... I
suppose that's what I'm trying to say. :)
