#DIFFERENCE IN UXTERM AND XTERM WINDOWS#

The VT xxx 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. 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.

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. #DIFFERENCE BETWEEN XTERM AND UXTERM WINDOWS# This is the window that contains the text cursor. Xterm provides usable emulations of related DEC terminals: The active window can be chosen through escape sequences, the VT Options menu in the VT xxx window, and the Tek Options menu in the 4014 window.

VT102 emulation is fairly complete, but does not support autorepeat (because that would affect the keyboard used by other X clients).ĭouble-size characters are displayed properly if your font server supports scalable bitmap fonts.

VT220 emulation does not support soft fonts, it is otherwise complete.

VT420 emulation (the default) supports controls for manipulating rectangles of characters as well as left/right margins. 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. 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). The alternatives after “xterm” are very old, from the late 1980s. VT100 and VT102 emulations are commonly equated, though they actually differ. The VT102 provided controls for inserting and deleting lines.

Similarly, “ansi” and “vt100” are often equated. These features differ in an “ansi” terminal description from xterm: acsc For instance, they use different controls for scrolling (but xterm supports both). #DIFFERENCE BETWEEN XTERM AND UXTERM WINDOWS#.
