I agree to the proposed semantics for CR, LF, LS, and PS. This would also
handle correctly the widely exploited CR-LF convention.

However, for FF, I'd prefer the following semantics:
  FF: wait; column=1, row=1; clear;
  wait : wait for some system-dependend acknowledgment from the user,
         e. g. hitting a particular key,
         or for some user-definable time, defaulting to about 10 sec
  clear: clear from current position to end of the screen

Best wishes,
