 Jim,
That could very well make sense, for in the formatting, as I remember it,the formal message traffic would have several CRs, then LFs followed by the NNNN sequence.

What I don't know, was exactly what was encoded in the mechanical stuntboxfor the M28 systems.

In some of the W.U. Plan 55 logic the required end of message was
LF preceding the NNNN
