What file transfer protocol do I use when sending an S-record file when I issue the loads command ?

I tried with both TerraTerm and Hyperterminal.

In Terraterm, when I use File | Send File ...,
In HyperTerminal, I use the menu Transfer | Send Text File ...

In both these cases, it reads the first line correctly, but by the time it wants to process the following line, it ends up reading garbage. It looks like the terminal programs kept sending bytes while U-boot was processing the first S-record line (which is an S0 record).

I also tried sending a file with the protocols Xmodem, Ymodem, Kermit.
Thy do not seem to work, or it is getting garbage (i.e. protocol specific headers, where it expects to see the actual S-record).

Our U-boot is based on 2008.10.
