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.
