If you've implemented your own read method then the dos/unix line mode
stuff won't happen, unless you've implemented it, IIRC.  Theoretically,
devices should be controlled by the CYGWIN=binmode setting.  It would
be kind of cool to allow mounting of the device to control the mode
but I think this only works for disk files.

I'd just trace things from _read() and see how it works.  Or, write
a simple program to check it.
