U seem to have a much different problem than I had, because: The "dd" command merely reads from /dev/cxm0 as fast as possible without any delay (e. g. due to busy network or disc), since /dev/null is quite quick... So I did not send my "cxm-network-transfer&buffering-tool", because one side of it does nearly the same as the "dd" command, and because my box was able to do the "dd" test for many hours... -Arne __________________________________________________ Do You Yahoo!?
