From: jer@x10sion.com (Jeremy Garff) Subject: non-blocking io on serial 25 Nov 1997 04:43:46 -0800 Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII To: gnu-win32@cygnus.com 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?
