Actually TUNEPORT was on my level 1 NitrOS9 image but I haven't tried using it yet

Gene,

If my memory serves, TunePort was a Level 2 programme, and was not available in Level 1.

  Chuckle, yes I can imagine Bob.  Its bad enough when two different dialects 
  of English are talking.

  However I would add the caution that the printer driver, unless it has been 
  fine tuned, needs a tuneport session in order to get above say 600 baud, 
  with enough baud rate accuracy.  I don't know if its because I have a 6309 
  in my coco3 or what, but at 9600 baud, the default bau=6 actually gets me 
  about 15 kilobaud, and tuneport says the default timing is '13' but to get 
  9600, I have to use a value of 29 or 30.  This checked by the timebase of 
  my oscilloscope, something that not every one has.

  In my case, I could disable my script on this machine, then watch the leds 
  on the adapter and tuneport till a valid speed is obtained as evidenced by 
  the data leds on the adapter.  If the speed is off by more than a few 
  percent, the leds go dark and no data is sent.  Sort of the hard way, but 
  it could be made to work.
