Hi, Paul.

Oh, which aren't?

Why do I need 2 quotes? p69 says re the ATZ command (inter alia) "Use
the parameters stored in nonvolatile memory to set up operating
characteristics." If we assume not unreasonably that
"parameters" means
"all parameters" and "operating characteristics" means
"all operating
characteristics", and if I assume that the Spirit uses the the ATZ baud
rate and not the one retrieved by the ATZ (I can't be bothered checking
this, and I'm assuming from the comments from you and others in this
thread that this is the case) then yes, the Spirit implementation does
not conform to its documentation. IN A LEGALISTIC SENSE, as I said
above. But it's still the right way to operate, it's just not documented
that it does that.

PE> FM> But it's the Courier that's fucked by design.

PE> Very true.

PE> DD> Isn't the Courier the only modem behaving as documented?

PE> FM> Yes, if all those things are true.

Well obviously I haven't seen the USR documentation. I can only go on
what's been discussed here, and in particular David's "if" scenarios at
the top.

PE> FM> But if so it's the design that's
PE> FM> fucked, in that it does not conform to what users expect, and can

PE> Yeah, regardless of the legalese smokescreen put up by USR bigots,
PE> the fact remains that the modem is fucked by design.

I agree of course. But it does conform to it's documentation, assuming
that says something like the Spirit does on "restoring operating
characteristics".
