> 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

>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
