Original Text
-------------
   DUPLICATE ACKNOWLEDGMENT: An acknowledgment is considered a
      "duplicate" in the following algorithms when (a) the receiver of
      the ACK has outstanding data, (b) the incoming acknowledgment
      carries no data, (c) the SYN and FIN bits are both off, (d) the
      acknowledgment number is equal to the greatest acknowledgment
      received on the given connection (TCP.UNA from [RFC793]) and (e)
      the advertised window in the incoming acknowledgment equals the
      advertised window in the last incoming acknowledgment.

Corrected Text
--------------
   DUPLICATE ACKNOWLEDGMENT: An acknowledgment is considered a
      "duplicate" in the following algorithms when (a) the receiver of
      the ACK has outstanding data, (b) the incoming acknowledgment
      carries no data, (c) the SYN and FIN bits are both off, (d) the
      acknowledgment number is equal to the greatest acknowledgment
      received on the given connection (SND.UNA from [RFC793]) and (e)
      the advertised window in the incoming acknowledgment equals the
      advertised window in the last incoming acknowledgment.

Notes
-----
There is no such thing as TCP.UNA in RFC793.  The boundary between acknowledged and unacknowledged sent data is SND.UNA.
