Try "cmp /dev/rfd0 /dev/rfd1".  Just a guess.  Unfortunately, this is
likely to take a fair while if it works like the RT does under AIX,
because blocking will fail.  To make things work better, use dd to
read the files and specify a large ibs= which is a multiple of 512.

Ed Clarke (hi, Ed) suggested using diff.  cmp should be significantly
faster, and is probably a better fit for "byte per byte" comparisons.
