When I first started with SLIP, then PPP, one of the cardinal rules given to me by Terry Lambert was "turn off modem compression completely." Reasons for this edict I've garnered over the years include: 3. Modem compression, as you have noticed, often interferes with VJ compression used in SLIP and PPP implementations. 2. Modem compression often interferes with, and lengthens transfer of, compressed files such as .gz and .jpg. 1. Modem compression slows down turn-around time -- terrible for interactive sessions. Anyone else care to expand this to a "Top Ten"? -- Wes Peters | Yes I am a pirate, two hundred years too late Softweyr | The cannons don't thunder, there's nothing to plunder Consulting | I'm an over forty victim of fate... wes@intele.net | Jimmy Buffet
