BG> Nope, the anomaly occurs because the USR doesn't
BG> auto-baud its serial port on an ATZ command.

IS> Indeed, part of what ATZ does (and arguably _should_ do) is restore the
IS> AT&W's port rate, as it restores all the other saved &W settings, no?

No, particularly when only USR modems do it like that, and there is no
good reason for not using the speed determined from the AT letters on
the ATZ command after the ATZ has been executed. Its got a real capacity
to bite you on the bum when the ATZ ALONE behaves differently there, and
non USR modems dont do it like that, and there is no good reason to do
it differently to how the other modems do it. Including a Hayes.

BG> However, I'm still not convinced that what Paul's complaining about is
BG> buggy behaviour insofar as all USRs function in this manner and AFA I
BG> can determine, always have done (my 1988 Courier HST/2400 certainly does).

IS> Agreed - that was my point, too.

It still has to be justified why it makes any sense for USR to
be doing it differently to other modems for no good reason tho.

IS> Sounds like it's just not the right modem for his
IS> (or Rod's) personal tastes.  Can't please everyone, so ..

Its not a question of pleasing everyone tho if there is no good reason
for USR to do it differently the way other modems do it on the ATZ ALONE.

The last thing we need is quirky little gotchas like that
when there is no good reason for doing it differently.

BG> If this was a true bug, I'd expect USR to have done something about it.

Corse its possible no one has bashed them over the head with the
fact that hardly anyone does the ATZ command alone like they do too.

BG> After all, I'm sure that Paul isn't the first person to have discovered
BG> this peculiar quirk.  Anyway, I'm currently awaiting the definitive
BG> answer from USR themselves, and will let you know what they say.

IS> Goodo.  I rather doubt USR will consider it either peculiar
IS> or a quirk, but it'll be interesting to see their reasoning.

It has to be if the bulk of other modems dont do it that way.
Particularly when its subtle enough to bite you, ONLY when you
have JUST ATZ as a modem init string, AND you change the port
speed from the one you last did a &W command at.
