[Users] Help with IBsim

[Robert LeBlanc]

Thank you Hal and Al, I did try the nodeid with the H-xxx, but the trick
was the quotes. I'm used to only using quotes when there are spaces in
argument, I'll have to remember this quirk.

As far as the fifo (not my strong point), I suppose I would just set up a
fifo in the shell, start up ibsim and then !<name of fifo> and then
echo/write the commands into the fifo. Does that sound right?

Thanks again!
