These are terminal standards. Sorry. > No. There are no ANSI, nor DEC nor AT&T nor IRIS, nor IBM, nor any other terminals that have screen-blanking capabilities. These are the inventions of later-date emulations. If my DEC VT-220 screen went blank I would need to have it serviced. This is a PC invention that was adopted by Linux. It's very poor design to have screen blanking enabled as the default. It's a feature that should be enabled if wanted, not forced. If you are not on-site within 10 minutes of having a remote system fail, you can't see what's on the screen when you plug in your monitor because the console driver has dutifully blanked the screen. And, you can write escape sequences from a task that doesn't exist. If `init` or whatever substitutes for it fails to execute, unless you are watching, or can observe the result before the screen blanks, you can't see what happened. It is very poor design. If the machine had blanking disabled by default, then the usual SYS-V startup scripts could execute setterm to enable it IFF it was wanted.
