Attached is the acarsd.ini file that I am using on an experimental node in Boston, MA. Though it decodes very effectively, I am not happy with ACARSD on Linux - not stable, crashes a lot. I used to run an ACARSD node on Windows, and it was much more stable on that platform.
I am not motivated enough about ACARS to put a separate machine there for ACARS. Furthermore, the acarsd software does not appear to be a maintained project any longer.
It's always fun to dabble with, perhaps I will bring a node up here at home to pick up airborne stuff, but probably not.
Too many other projects that are more interesting and useful.
Hope the .ini file helps you get decoding.
