non-blocking io on serial

I figured out how to get the serial port open for reading under NT. It
was fairly easy, I changed the device name to com3. It appears that the
tcgetattr and tcsetattr function are in the cygwin libraries, since I was
able to link the code without problem. Unfortunately it seems they don't
work as they do in UNIX. I am setting the handle to non-blocking mode and
to wait for a period of 1/10 of a second or so. When the program executes
under windows the read call blocks forever. Is there a way to set a
handle to not block under NT with tcsetattr?
Thanks in advance,
