[Jython-users] Read/write serial data

[James K. <jwk...@gm...>]

Hi,
I'm aware of the fact that I'm about to ask a lot of the group but I do
need the help. I dabble with programming but have to acknowledge that what
I need is beyond my abilities to develop; so I hope the group will take
mercy on an old retired model railroader.
I have an Arduino that I need to pass ASCII to/from a computer through a
USB COM1 port.  I want to use Jython as I am running Win-10 with a JRE.
I find a lot of code samples, most using the RXTX library, but nothing
demonstrating a way the user can input data to send and and at least a
print statement to show the ASCII input. Most code seems to be in Java and
I know from reading that it can be used from within Jython.
I'm old school (before OOP) and to be honest I find the code snippets to be
confusing. Is there a working example on-line or in a reference book that
demonstrates what I need -- start to finish?
