+> RedBoot supports both serial ports, which are available via
+the stacked serial connectors on the mother board.
+The topmost port is the default and is considered to be port 0 by RedBoot.
+The bottommost port is serial port 1.
+The default serial port settings are 38400,8,N,1. </P
+><P
+>FLASH management is also supported, but only for the FLASH device in IC7.
+This arrangement allows for IC8 to retain either the original Fujitsu board
+firmware, or some application specific contents.</P
