[Coco] Using Rick Adam's DELPHIterm 3.1 to connect a Coco3 to a TRS80 PT210

[Arthur Flexser]

PRINT #-2 is creating the same thing (a sequence of byte values) as a
terminal program outputs for text.  The problem is likely either that the
baud rate disagrees with the one the printer is expecting, or else that
Basic's printer output routine isn't receiving the "printer ready" status
that tells it that the next byte can be transmitted.  This check for
printer status can be knocked out with a poke or two that I don't have
handy, but I'm sure someone can tell you what is needed for that.
