You can only give RedBoot commands on a single "console" port.  Once
you enter a command on one port, RedBoot will only interact with you
on that device until you change it (reset the board or use the "console"
command to change ports)

Which device did you use for the "load" command?  If you did it on
the keyboard (with CRT display), this won't work as it will be expecting
to see the X-modem data on the keyboard!  You could try using the "-c N"
switch (most likely "-c 0") to force it to read via the serial port.
