You shouldn't ignore that too much. The input to SETMODE is not the same
as the output of SENSEMODE (i.e., you can't just do a SENSEMODE, set/clear
some bits are do a SETMODE) if you plan on messing with baud and/or frame
size. DEC really screwed this up something awful. I can send you some
details if you are interested (all the programs I have that deal with this
are written MACRO-32).
