Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-realtime@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?

Seems like it'd be a fine place to work if I didn't have having to go through RTP traffic in the afternoon. >Why is there a link to openbsd there, does openbsd have some realitime >extensions? Yes OpenBSD does have realtime extensions: RTMX. Obviously those extensions are not in the OpenBSD tree; they're in the private RTMX tree. I did hear a whisper about those realtime extensions being released to the public, but I don't know if that will ever happen. (sorry about the crosspost) -- XCOMM Kevin P. Neal, Junior, Comp.
