You'll have seen the "Soft Ports" node in the manual, it's pretty
straightforward.

If it's for a lot of bytes, then the scheme-level bits will be very
slow (read/write only 1 byte at a time) and you might have to break
out some C.  (Getting that C level bits into scheme would be a good
thing one day.)

For reading OLE file contents I did my own read func.  But whether
that's good probably depends what and how much other code is going to
use the port.
