Because, for file transfer (like, say, oh maybe news batches?) compress
works better than MNP compression. Leaving the MNP compression enabled
for compressed files loses big time.
MNP error correction is another question. I haven't seen any
numbers, but if the speed penalty is less than a percent or maybe
two it would be a win on very noisy lines.
These comments apply to uucp. The whole thread applied to
uucp. Just look at the Subject: line.

caring, is to become part of a process, to achieve an inner peace of mind.
The motorcycle is primarily a mental phenomenon." -- Robert M. Pirsig
