:-) I have downloaded and had a quick look, and I see it is based on the
standard library's serial.Serial class - another battery that I have not used
before. And I see that serial.Serial looks like it uses os. calls, which is
one of the things Greg mentioned. Curioser and Curioser.
There was one thing I saw in a quick read of pyserial that I did not like as
I cannot understand why it is done - if a timeout is set to less than a
tenth of a second, then it is changed to be a tenth. - In a polling protocol
that will limit you to poll only ten terminals a second, or less, and is a
very long time if a message takes only a couple of millis to send.
I am getting there - this time around I want to kill this problem dead because
I seem to keep doing something wrong somewhere and I want to understand what
it is and stop doing it.
