I don't think so, but I'll check. I think all I did was set cold=1
and rebuilt. Make sure you use my "eae" version of simh.
I'm building with the v7 asm and using "ml" to process the a.out

That looks ok. I don't have tc setup, but that should not matter.

same here, but I don't add the "-" (not sure what that does)

Try "det rf". I noticed that the RF device is buffered in ram
and I'm not sure it gets flushed until you detach.
