.POS files are in the spec? I thought they were an application-specific
feature, not an APRS specification. Does that mean that my object file
format and my configuration file formats, and everything else about my
APRS client needs to adhere to the file format specifications of all
other APRS clients?
I only support .POS as a form of backward-compatibility with earlier
clients, not as a spec-compliance item.
What are specs, what are extensions, and what are options? It seems to
be getting grayer and grayer every day.
