I think its safe to use "read" now. ah ok, thanks. >Btw, I built from latest sources and installed into simh and >ran and got some action on rf0 but I don't see any non-zero bytes >in the image after running.

Make sure you use my "eae" version of simh.

I don't have tc setup, but that should not matter. >I built as "as - sys1.s u?.s". same here, but I don't add the "-" (not sure what that does) >I run with "go" and then after the first halt "go" again. Hitting >^E after waiting a while shows that its looping in panic. Try "det rf". I noticed that the RF device is buffered in ram and I'm not sure it gets flushed until you detach. -brad
