Sattler. 1) Do not include the DECSLRM or DECFRA features for xterm; they will be added instead if secondary DA responds as VT420 (this happens already). 2) Set or reset the individual flags after terminal-overrides is applied, so the user can properly disable them. 3) Add a capability for DECFRA ("Rect").
