Do it from userland and fifo it to RTL. That's my advice. And if
you do this, you might as well use Perl or Python to connect since
it's very simple and convenient.
That's my opinion too. I do this without any problems in a project for a
machine control. Using three fifo's (one for the commands to the rt-module,
one for commands from the rt-module to user-land and the final one for
logging purpose from rt-module into user-land). A small perl-script is
capable of acting like a communication bridge between the fifo's and e.g.
the gui-sockets (also written in perl).
It select's on the fifo's and sockets, restart's them if neccessary and so
on. Everything is working fine and you can attatch other parts via sockets
very easy, monitor and log the traffic, handle accesss requests and so on
without disturbing or modifying your critical rt-module.
As soon as I refine my project I'll be able to extract the main part as an
example, if anybody is interested in.
