[comp.dcom.modems] Hayes v.32

I just recieved one of the Hayes V.32 9600 baud modems.  I was under the
impression that V.32 had error correction and data compression and thus
could provide better than 9600 throughput.  Also I was under the impression
that V.32 supported some level of MNP.  I have been going through the manual
and there is no mention of either of these featues.  I also have a Hayes
9600 V.42 It has data compression and error checking if you are talking
to another v.42 but at least in has MNP level 3 so I get slightly better
throughput than 2400.  I really just need a modem that I can use for BBS
and Network telecomunications and figured that I might as well get one that
wouldn't get outdated quickly.  Please don't tell me I would have been
better off getting a much cheaper HST dual standard.

No, you are confused.  "V.32" only refers to the details of the "analog"
signalling between the modems.  "Transparent" error control and protocols
like MNP are "layered" on top as suits the modem vendor.  The V.42 stuff
represents an attempt to standardize one such feature suite...
