Where are baud rate settings documented? I can find
pinouts for assigning
signals on the DB25 connector, but not a mention of baud rate.
I know very little about N* machines, but if it uses a separate baud
rater generator circuit (seprate that is to the serial chip -- and I seem
to rememnber 8251s in there which always use a separate baud rate
generator), then a useful trick is to connect a 'scope or frequency
counter to the transmit and receive clock inputs on the serial chip. In
most cases the buad tate is that freqeuncy/16. It's posisble to program
some serial chiss for divide-by-64 (and other values have been used too),
but most of hte time its divide-by-16.
