The Tektronix text and graphics commands are recorded internally by xtermand may be written to a file by sending the COPY escape sequence (or through the 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. (See the "Xterm Control Sequences"document.). Many of the special xtermfeatures may be modified under program control through a set of escape sequences different from the standard VT102 escape 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). You may also use \*(``vt220,\*('' but must set the terminal emulation level with the decTerminalID resource. Termcap (5) entries that work with xterminclude an optional platform-specific entry, \*(``xterm,\*('' \*(``vt102,\*('' \*(``vt100,\*('' \*(``ansi\*('' and \*(``dumb.\*('' xtermautomatically searches the termcap file in this order for these entries and then sets the \*(``TERM\*('' and the \*(``TERMCAP\*('' environment variables. The VT220 emulation does not support soft fonts, it is otherwise complete. Double-size characters are displayed properly if your font server supports scalable fonts. The VT102 emulation is fairly complete, but does not support autorepeat. The active window can be chosen through escape sequences, the \*(``VT Options\*('' menu in the VTxxx window, and the \*(``Tek Options\*('' menu in the 4014 window. This is the window that contains the text cursor.

This box is located in the upper left area of the window.Īlthough both windows may be displayed at the same time, one of them is considered the \*(``active\*('' window for receiving keyboard input and terminal output. To maintain the correct aspect ratio (height/width), Tektronix graphics will be restricted to the largest box with a 4014's aspect ratio that will fit in the window. The VTxxx and Tektronix 4014 terminals each have their own window so that you can edit text in one and look at graphics in the other at the same time. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized. It provides DEC VT102/VT220 (VTxxx) and Tektronix 4014 compatible terminals for programs that cannot use the window system directly.
The xterm program is a terminal emulator for the X Window System.
