Hi,

>From the screen man-page (i.e. without having tried it :-):

              exec !.. stty 19200
              exec ! stty 19200
              !!stty 19200

       Set the speed of the window's tty. If your stty command
       operates on stdout, then add another `!'.

You probably can use

  bind B exec ! stty 19200

That should set the baud rate to 19200 when typing Ctrl-A Shift-B
(which is not bound by default as far as I can see).

Hope, this helps.

                Kind regards, Axel
