            Unrelated to this issue, but possibly to the framing errors:
            I've also removed the NMEA log filter from
            modem::StandardLineHandler() and found after normal GPS
            startup, the NMEA sentences always come in three times via
            three MUX channels – additionally to channel 1 on channels 3

              Another theory: I found Mark's comment in the SIM7600
              driver NMEA startup:<br>
              <br>
                // We need to do this a little differently from the
              standard, as SIM7600<br>
                // may start GPS on power up, and doesn't like us using
              CGPS=1,1 when<br>
                // it is already on. So workaround is to first CGPS=0.<br>
              <br>
              IOW, the SIM7600 may have GPS enabled by default, possibly
              also sending NMEA sentences, if not explicitly switched
              off.<br>
              <br>
              BTW, that also explains the difficulties in booting a 3.3
              module from USB… :-/<br>
              <br>
              a) We don't switch off GPS if GPS is disabled.<br>
              <br>
              b) I just tried switching off GPS manually after a
              GPS-enabled startup, and the modem still continued to send

                  Craig's observation makes me wonder... Does the gps
                  system produce interrupts which are not handled
                  properly when gps is turned off. Unhandled interrupts
                  might get constantly repeated causing the IDLE tasks

                I think that may be the case. Maybe the NMEA MUX channel
                gets continuous input from the 7600 when GPS is
                disabled?<br>
