Indeed it is. The color version is the VT525. I haven't found the technical manual for VT525, but the user manual mentions as one of options in the configuration menu: "Erase text to the text background color (PC style)" "Erase text to the screen background color (VT style)" However, to a very large degree this is all moot. We have done it one way for 17 years, and that is the terminal emulation that is expected when $TERM is "linux". Realistically, if we want to introduce a new xterm-compatible mode it needs to be just that, a mode; and then we can set TERM to "xterm". -hpa
