Such wild speculations that are not based on personal experience or
knowledge are not really helpful.
U-Boot does not implement any kind of flow control on the serial port.
For S-Record download, there is some basic synchronization based on
the echo of the input that it sends back (assuming CONFIG_LOADS_ECHO
is set in the board configuration), but this requires a terminal
emulation that understands how to handle that. This is why the manual
recommends "cu" and "kermit".
Best regards,
Wolfgang Denk
