    Perhaps this indicates that Emacs thinks there is some operation every
    device should support, and HS: fails to do so.  I believe I had to make
    DP: support FILLEN, RFDATE, and LNKEDP before Emacs would work acceptably
    with it.

Yeah, EMACS used to die until I supported LNKEDP, but this is something else
