        Most people with troubles in Allegro's RS274X can solve
        those issues by reading the fine manual.  I suspect the
        "dropped pads" issue is related to the software doing
        exactly what you tell it.  Granted, it is a little non-
        intuitive what exactly you should say...

        We have been using it for some time and after some teething
        troubles circa 1997, we have not had a reliability problem.
        Yet.
