Ah- that certainly sounds like what's going on!
Thanks, mtempsch, I'll have some fun poking around with Hyperterm again tonight.
I'm not certain that I ever got the shell prompt- normally this would come up after boot up and hitting the [enter] key, no?
That's the way Hyperterm works for me with my ABB robots.
Shouldn't I see a "->" for a prompt? But I never got one... hmm.
Nevertheless, the RAM test functioned properly when I hit [ctrl]T, so I betcha [ctrl]C will also work.
I'll post again tonight after a few more tests.
