- Such a feature would be nice.
-
- Another thing that would be useful is a way to push (flush) the
- current v.42 packet out of the modem. This would be very useful at
- the end of TCP packets, to cut down on a bit of the delay.
-
- I wonder if any modem manufacturers is doing work in this regard.
