+SBUS Issue
+----------
+
+When the dedicated SBUS output port is used on boards with a IOMCU
+(such as Hex Cube or Holybro Duandal) then SBUS would be interrupted
+on loss of RC input. The problem was that the same UART was used for
+both SBUS output and RC input. When RC input is lost the RC protocol
+system starts searching for a receiver, which involves changing
+baudrate on that UART. That baudrate change affected SBUS output. This
+means if your aircraft depends on SBUS output to fly and you get an RC
+failsafe you risk losing RC outputs. The fix is to not change
+baudrates on that port when SBUS output is enabled (which means
+protocols like FPort can't be used when IOMCU SBUS output is used).
