Isn't V.42 just another data compression/error correction standard?  Not really
superceding V.32, but just replacing (or coordinating with) MNP4 and 5?  I 
thought it was a standard for end-to-end error correction protocols.  Wrong?

That is, doesn't it really replace MNP4 (or whatever) with a slightly more
comprehensive scheme which includes the MNP protocol?
