  Multiprotocol Transceivers Combine RS485 and RS232 in a
  Single Device to Simplify and Shrink Applications that Use
  Both Standards
  Steven Tanghe The RS232 and RS4851 data transmission interface
  standards are in widespread use today despite their
  relatively advanced age—RS232 was introduced almost
  50 years ago; RS485, 30 years ago. Such longevity for
  any standard is uncommon in today’s rapidly changing
  electronics landscape, where consumer demand
  can force obsolescence in a handful of years.
  Although the once ubiquitous RS232 port
  on personal computers has largely been
  replaced by USB, RS232 continues to proliferate in applications requiring rugged,
  short distance, point-to-point communication, such as in sensors, test equipment,
  device programming and diagnostics.
  Likewise, RS485 thrives thanks to its high
  performance in harsh environments. Its
  differential signaling scheme and wide
  common mode tolerance provide excellent
  noise immunity, allowing high speed communication over relatively long distances.
  Perhaps equally important in the RS485
  standard is the ability to network several
  devices on a single bus, thereby reducing …
