To answer the original question, if you're running 3.1.4 you can create and
apply a modem table entry. Then, each time the port is issued a reset
command the modem gets configured using those settings. And to prevent
getting yelled at for again not supplying the complete answer, modem table
entries are created thusly:

add modem usr-v34 "USR Courier/Sportster V.34" 115200 system "AT&F1&W\r^OK"

(for example) and applied like so:

set s1 modem usr-v34
reset s1
save s1

Now then, it is a mis-statement to say that when &D3 is set the modem will
latch its DTE rate to the last known DCE rate, if your modems are doing
that they have a bug and your modem vendor owes you an upgrade. In fact,
the response that setting the &D register to 3 is quite correct.
