To be sure, this is not meant in any way to be a Unication basher. I love the radio and promote them all the time. Here is how I see it. The FW code writers had to write this error into the code or it would not show up. Therefore it clearly has a meaning.
Not really. You CAN program the application / firmware to pass on the error. They didn't necessarily write "Error 32" for example, but that may be whatever language they wrote the firmware in passing on an error.
For example, I worked at a software company a LONG time ago (early 90's). We stored a particular data in a text file, comma deliminated.
An error started creeping up - thank you ADD, I remember the error - "Input past end of file."
What did this mean? It means the program expected the file to end after a certain place, but somehow a 'blank' line was inserted at the end of the file, and since that line didn't have data, it was unexpected. We didn't 'write' "Input past end of file", but the programming language threw the error since we basically said "Display whatever error comes up."
