Well, I have a program I got from somewhere, called "prtty", which does
intelligent baud switching before handing off to getty.  I have been
unable to reach the author for some time, but the notices make me think
I can redistribute the source.

It requires a verbose modem, which will tell it what baud rate to switch
to. Prtty takes care of the rest.  It also makes the line useable in both
directions, since it can detect unsolicited traffic on the line and
go away until the line is no longer in use.  These switchovers take a
little time, but they have been very reliable on my machine.

I have been using this for some time, with HDB and a telebit.  Without
prtty, I had no end of trouble with the 'blazer.  With it, I have been
without a glitch for a very long time.
