I have had damaged GIF files that gave a warning in LView, and, when
displayed, show some anomaly, like a red line, or something.
As far as non-error checking, I don't think you can turn off Kermit, but
there is a non-checking protocol in the XYZmodem family. I think it is
Ymodem, that provides no error checking, relying on a clean link, instead.
This might be what you want.
