It makes NO SENSE WHATSOEVER, do be sending the word "OK" to
you at 38400, yet the word "RING" at 57600.  No terminal can
possibly be set to both baud rates at the same time.

No, what you actually read (somewhere) is that IN THE ABSENCE 
of an AT command, an incoming "RING" will be sent to the
terminal at the speed of the last AT&W.  The modem doesn't
know what the speed is, because it hasn't received an AT
command.  The speed of the AT&W is PERFECTLY FAIR, and a 
BLOODY GOOD GUESS.  However, the moment you get an AT command,
you KNOW what the REAL speed is, and you should adapt to
that rate.  As it does, for everything except the RING.
BFN.  Paul.
