 for full-duplex
From The Free On-line Dictionary of Computing (30 December 2018) :

  full-duplex
  fdx
  
      (fdx, from telegraphy) 1. A type of
     duplex communications channel which carries data in both
     directions at once.
  
     On purely digital connections, full-duplex communication
     requires two pairs of wires.  On analog networks or in
     digital networks using carriers, it is achieved by dividing
     the bandwidth of the line into two frequencies, one for
     sending, and the other for receiving.
  
     2. An obsolete term for remote echo.
  
     Compare simplex, half-duplex, double-duplex.
