/* properties_t: Type of properties that can be detected on a device
This structure lists all the properties that fxlink can detect on connected
devices. These properties help identify the devices in interactive use, and
accurately specify which calculators to interact with when several models
are connected simultaneously or when the same command in run against
different models in a script.
Depending on the backend and access privileges, not all properties can be
detected. The backends supporting each property are listed in brackets at
the end of each description.
An instance of this structure can also be used as a filter. In order for the
semantics of filtering to work out, every attribute needs to have a "total
information order", meaning that two values can be compared for how specific
they are. A device will match a filter if and only if all of its properties
are more specific than the values provided in the filter.
Currently the order is "true more specific than false" for all booleans and
"any value more specific than NULL" for the serial number. Properties that
cannot be detected by back-ends are reset to their least specific value (ie.
ignored). */
