   Wow that's both good advice for Amiga folks as well as just interesting to   
   know in general.  I just went to check out Amiga pinouts to see just what all   
   the serial port could handle, and apparently different models had varying   
   capabilities, everything from audio in, audio out, the various power voltages   
   you mention, interrupts, and even the system clock.  That's actually pretty   
   awesome from a tinkerer's perspective.  Might have been a headache for people   
   to use standard cables with, though, until they made sure it was ignoring   
   those other pins instead of passing them through.
