In addition to the text, the manufacturers wanted non-text (invisible) ways of invoking terminal-specific behavior, thus, "control characters" and "escape sequences". Some were paper and ink ribbon, some were "glass keypunches". You should be able to get the list using toe, toe /usr/share/terminfo, or find $%/%2.2X\E\\', NULL.īack in the old days, "terminals" were separate devices. The full list varies from system to system.
For example, vt100 doesn't seem to support F11 and F12.Ĭompare their features and escape sequences that your system thinks they have by running infocmp, e.g. In the same way, vt220 has more features than vt100. You can test this by pressing z inside top. For example, xterm usually supports colors, but vt220 doesn't. Xterm is supposed to be a superset of vt220, in other words it's like vt220 but has more features.
