The protocol used by the RDC (as far as I know) was very closely held.
I couldn't get any docs on it in Field Service (I wanted to write a
CP/M program so my VT180 or Zorba could be a remote console and diag
loader on the 11/70's.

I was told they were doing ascii bit flips on at least one bit on each byte
but I never got the datascope on the line to see what the protocol
looked like.
