-  How big is RX FIFO within HAL? 32 bytes
-  Is there a 'nearly full' interrupt for the RX FIFO?
-  We could check the RX FIFO empty bit in the ISR in a loop
-  We could increase the ISR priority level
-
   ISR is currently 16us which supports 460800. We can burst mode to 8.5us.
+
+  With the most recent pull of the Apollo3 core from Github (ISR reduced, buffers
+  increased to 4096), and a 512GB card, this sketch can correctly receive/store
+  non-stop serial at 500000bps. Burst mode is not needed.

+  691200bps is possible in burst mode
