I don't use MS-STAC. It wouldn't work for anyone but Win95 users WITH compression
on-at least that was the case a year ago or more. Haven't messed with it since.
Back then, we
tested STAC against NONE extensively, found STAC to be faster overall, nailed it
down
and forgot about it. With the user's compression off, the only side effect is a
longer time-to
login (few seconds) and V.42 seems to be doing it all for them. With compression
on the user
side, net login snaps right through and they pick up a notch in download speed.
Consistently
repeatable here, though of course it doesn't show up as drastically on
near-perfect connect
speeds, 31.2 - 50K as it does with the 26.4 connects. We have some VERY rural
users.
