I've been following the discussion on MNP, etc. and have a question
about MNP4's operation. I know it packetizes data into "HLDC-like"
frames, and uses an ARQ protocol. What I'd like to know are:

  1. What is the maximum frame size?

  2. Does it do windowing or just stop-and-wait and, if so, what is the
     max window size?


The bottom line is: On an international link which may be subject to
satellite delays, is it better to use MNP4, or turn it off and use a
software protocol like windowed kermit?

Would V.42 be better than MNP4 in this regard?


Thanks for your help.
