[c-nsp] xmodem file transfer

[scott owens]

If you have to do this again - you can change the baud rate to either 57600
or 115200 and change your comm software.
and you can do a xmodem-1K xfer which is somewhat akin to jumbo frames via
serial .

dont forget to put back to 9600 at both rommon & config
