Re: RTlinux problem

Thanks Ray,

Your post exactly describes the problem and solution - I wasn't aware of the
post you quoted but, following advice from Hugh Currin, I did a chmod u+x
rmrtl insrtl and all the examples immediately came to life - more than I got
on the 2.0.36 kernel version, I never did get more than the 'frank zappa'
one to work on that machine. The two files in question are both situated in
the 'rtlinux-2.3' directory

two files that needed permissions changed before it would let me see the

rtlinux-2.2 directory.
