And suffers some rather short cable length limit, ISTR 5M single hop and
a maximum of 6(?) cascaded lengths if you fit repeators. In the real
world 5M hardly gets you from one desk to another. It certainly won't
reach from my PC to the current UPS location in the other corner of a 3M
x 3M room for example. Serial does this without a problem, like wise the
15M between the logging PC and the Automatic Weather Station.
