BG> I've just spent half the morning replacing EPROMs,

Just think how much more convenient that would

Its basically just the usual excising of modem inter operability warts
on the handshake failures if they really have gone for good with the V43+
roms. Presumably seen rather more on your type of very ordinary line.

The same thing happened with one rom change in the Supra
V32bis roms too, helped the handshaking very substantially.

BG> Interestingly, I referred back to some of my press releases from
BG> USR, and they actually stated at the time that the V.34+ upgrade
BG> EPROM had been improved so dramatically, that users could expect
BG> at least one 2400bps step improvement in link rates, and in some
BG> cases, as much as 2 x 2400bps steps.  This actually correlates
BG> quite accurately with the results I'm seeing here too.

Sure, but thats a completely separate issue to handshaking failures.

AND its hard to say how much of that is poetic license on the
speed stuff too, it may well be what actually happened is that
its just fixed some blemishes in what they did before that. USR
has always been very reluctant to admit they have fixed a stuffup.
