Basic serial has its merits, but it's regrettable that RS-232 came out 
on top. RS-422 (or full-duplex RS-485, not much difference) would have 
been a much better choice. Differential so it has good noise resistance, 
and it doesn't use weird voltages (-12V? come on...)

It all looks the same from the software side though. Bytes in, bytes out.
