Not all of the features described in this manual are necessarily available in this version of xterm. Where yyyy, MM, dd, hh, mm and ss are the year, month, day, hour, minute and second when the COPY was performed (the file is created in the directory xterm is started in, or the home directory for a login xterm). The name of the file will be “COPY yyyy- MM- dd. The Tektronix text and graphics commands are recorded internally by xterm and may be written to a file by sending the COPY escape sequence (or through the Tektronix menu see below). There is no write-through or defocused mode support. Four different font sizes and five different lines types are supported. It supports 12-bit graphics addressing, scaled to the window size. The Tektronix 4014 emulation is also fairly good. Many of the special xterm features may be modified under program control through a set of escape sequences different from the standard VT xxx escape sequences (see Xterm Control Sequences). (The “TERMCAP” environment variable is not set if xterm is linked against a terminfo library, since the requisite information is not provided by the termcap emulation of terminfo libraries). On most systems, xterm will use the terminfo database. You may also use descriptions corresponding to the various supported emulations such as “vt220” or “vt420”, but should set the terminal emulation level with the decTerminalID resource. Xterm wraps text at the right margin using the VT100 “newline glitch” behavior.īecause of the wrapping behavior, you would occasionally have to repaint the screen when using a text editor with the “ansi” description. Pseudo-graphics (line-drawing) uses a different mapping. These features differ in an “ansi” terminal description from xterm: acsc For instance, they use different controls for scrolling (but xterm supports both). Similarly, “ansi” and “vt100” are often equated. The VT102 provided controls for inserting and deleting lines. VT100 and VT102 emulations are commonly equated, though they actually differ. The alternatives after “xterm” are very old, from the late 1980s. Xterm automatically searches the terminal database in this order for these entries and then sets the “TERM” variable (and the “TERMCAP” environment variable on a few older systems). ![]() Terminal database ( terminfo (5) or termcap (5)) entries that work with xterm includeĪn optional platform-specific entry (“xterm”), Xterm does not support some other features which are not suitable for emulation, e.g., two-sessions. VT420 emulation (the default) supports controls for manipulating rectangles of characters as well as left/right margins.
