The command has a multitude of options. If issued without parameters, the GET
variant is implied, i.e. the status of the SDI-12 subsystem will be returned (see also
below). The full extent of the commands is not given here as the the SDI-12
subsystem is configured via the wireless link by using the GUI configurator in the
A840 Telemetry Gateway. Additional information can be obtained from Adcon
Telemetry upon request.
