Fraid so.

Which Bink MUST be sending to the modem at 38400 as it starts
up and check if there is a visible modem. LONG before any RING.

He's right, totally nuts. AND non standard AT command behavior TOO.

BG> Not really.

Fraid so.

BG> It's a strange quirk with the USRs

It is indeed, totally fucked. The RING is supposed to
be sent out at the speed of the last AT command it saw.

BG> (dunno if it applies to Rockwells, I've never checked).

Nope, they do it right.

BG> All you need to do is run up your favourite comms app with the

BG> at around 4000 cps (which is too fast for a port speed of 38400
BG> anyway) - then do an AT&W to write this baud rate to NVRAM.

Sure, but you shouldnt have to.

BG> BTW, all you need as an init$ is AT&F1&W.  Then ATZ as your Terminit.

Yes, but you shouldnt have to. FAR to quirky a way to implement it.
Bound to keep biting people on the arse. Doing it the right way, always
sending the RING at the speed of the last AT command is MUCH more
sensible. Thats the whole POINT of the AT, its designed so the modem
can autobaud on those letters. Totally nuts to ignore the speed detected.
