                            |   ROCKWELL and SIERRA started and have adopted

                            |   so it makes it hard to determine what options
                            |   are allowed for commands
                            | +FAA=? works but +FAA? returns ERROR
                            | AT+FDCC? is missing the first entry
                            | You can't query the LID
                            | AT+FREL=? seems to think it's doing AT+FMFR?
