xterm? Never heard of it. In all seriousness though... sorry, friend - that's a negative re: xterm vt420 compatibility. Quoting from the [current] author's own website at invisible-island.net/xterm/ : "[xterm] also implements most of the control sequences for VT220, as well as selected features from other DEC terminals such as VT320, VT420, and VT520." That "selected features" bit is why I keep the real glass one around. Paging is probably the most deficient area that I really notice.
