DC Cable / Copy

When I send the Dreamrip.srec to the DC unit, nothing happens. I see the data being downloaded.
And then I change teraterm to receive the DC info, I let it run for hours, and nothing shows. And nothing is in the file.

BTW, does anyone know what the boot CD or the Serial Slave are written in?
I know they have been compiled.

Anyway, any info is greatly appreciated.

Thanks
