Clear to receive? Oh boy...lets use the officiall CCITT terms, Clear to
Send, so we dont confuse people more, okay?

Doh, again, its MNP 5 (microcom networking protocol - we actually beta
tested the first MNP 5 modems about 12 years ago). Both MNP 5 and v.42 bis
have a 4:1 compression max. MNP 7 had an 8:1 theoretical max compression
bu I dont think it was adopted. We had some actual MNP 7 modems a few
years back, cost us over $1200 each. Lets just assume that one was a
transposition typo. ;-)
Oh and one other tidbit, Microcom didnt actually develop MNP, the bought
another company, altho the name escapes me right now, and renamed THEIR
compression algorithms as MNP. Something like Advanced Communications
something...
Please check out this link for a brief explanation of all the
communications protocols:
