  Any V.22bis or V.32 modem does this....or any other phase
  modulated modem.  Async data is NOT transferred end to end as
  a bit stream.  It is converted to a sync format and xmitted.

  Any modem that needs to be configured for bits/character,
  parity and/or async DTE baud rate is converting the data...and
  recreating it at the far end.
