Note that %x is already taken (and is a synonym for %h)
Perhaps %i ? ( justification: when one uses ftp to transfer in binary mode,
it says:
ftp> bin

Perhaps $fwritei, as %x is already in use, and we suggect %i
above.

Note that the spec for reading binary values only reads in the
0/1 value, and not x and or z values.
Is this ok?
If so, then should $fwrite("%x",32'x); transfer 0?
