I understand the basics of how MNP and V.42 work, but I have never seen
anyone describe exactly how two modems negotiate a reliable protocol and,
possibly, compression.  How do they do this?  Does one end send a special
set of characters to the other end and look for a response?  Do they use
special tones or timing sequences?  If I am calling an intelligent modem
from a "dumb" one, what should I expect to see while the intelligent casts
about trying to figure out the capabilities of the modem on the other end?

Could someone post a short description of what goes on during the modem's
call setup.

Thanks,
