To allow easy access to the field loader, the power button may be used to switch
between the factory loader and the field loader and from the field loader and normal
operation. When this procedure is used with a serial adapter, the Baud rate will
default to 19200 and the Protocol will be both XON/XOFF and Ready/Busy.
Note 1: Do not attempt any other commands in field loader mode. You may
experience unexpected and undesirable results.
Note 2: If for any reason, the field loader is corrupt, the factory boot loader must be
used to replace it.
