  I think it should be pointed out that just because two modems support V.42
doesn't mean they can talk to each other at high speed. 
  V.42/V.42bis/MNP-5 are like ASCII (vs EBDIC - damn, I can't even
remember how to spell that IBM mainframe encoding standard. Which
letter am I missing??)
  V.32 is a CARRIER standard. One can run V.42bis over 300 baud
carriers if you so desire (unless the standard specifically outlaws that)
