There seems to be a lot of confusion about the difference between V.32bis and V.42bis. V.42bis is, I agree, pretty useless if your data is already compressed. V.32bis is yet another modulation scheme, this time offering (I think) a 14Kbaud full duplex data rate, but it's not yet widely available. -- Amanda Walker amanda@visix.com Visix Software Inc. ...!uunet!visix!amanda -- Remember: this isn't reality.
