I'm not a FreeBSD expert, but in "Dr. Dobb's Journal" #310 March 2000 (www.ddj.com) there is an article title "Real-Time Linux" that discusses 2 projects to bring real time to Linux. Perhaps these might also be applied to FreeBSD? Also, define "precise time measurements". What is the rate and granularity that you need? If your DOS system is "working", why do you want to "fix" it? <grin> Mentioned in the article: RTLinux at http://www.rtlinux.org, Real Time Application Interface, (an offshoot of RTLinux with better timers?) at http://www.aero.polimi.it/projects/rtai Cla. > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of > Gustavo Vieira > Goncalves Coelho Rios > Sent: Sunday, May 07, 2000 2:15 PM > To: Gilad Rom > Cc: freebsd-questions@FreeBSD.ORG > Subject: Re: FreeBSD as a Real-Time solution? > > > Gilad Rom wrote: > > > > Hello, > > > > I have been using FreeBSD as a Server OS for a long time > with great success > > and satisfaction, > > and now the need has come for a new solution to our > production network, > > which has several 486/386 machines, > > that need a real time OS to monitor production status. > > > > Question is, could FreeBSD be made suitable for such tasks? > > Performance isnt an issue, but I need to make precise time > readings from the > > parallel port > > and timing is critical.
