Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Take a look at http://www.rtmx.com Does anybody here have any experience with that os (note the openbsd link at the bottom of the page). I am going to go pick up a book on POSIX realtime, but should I be able to do the realtime type of operations I have written about previously? Generating a 500hz variable frequency (oxy) pulse train? Or reading in voltage inputs once every millisecond reliably. Is POSIX 1003.x what I am searching for? Why is there a link to openbsd there, does openbsd have some realitime extensions?
