Test the compatibility of so-called "VT100-compatible" terminals


Terminal emulator for the X Window System


The basic X terminal program


vttest - test VT100-type terminal


vttest [options] [24x80.132]


Vttest is a program designed to test the functionality of a VT100 terminal (or emulator thereof). It tests both display (escape sequence handling) and keyboard.
The program is menu-driven and contains full on-line operating instructions.
.IP o 2 To run a given menu-item, you must enter its number.
.IP o 2 Menu items start at zero; this is the Exit item in almost all cases.
.IP o 2 You can run all menu-items (for a given level) by entering an asterisk, i.e, *’.
.IP o 2 You can force a repaint of the menu items by entering ?.
.IP o 2 A few menus can be more than one page. Use n and p to switch to the next or previous page.


You can specify the screen geometry in the form [24x80.132], i.e.,
.IP o 2 24 lines,
.IP o 2 80 minimum columns, and
.IP o 2 132 maximum columns.
If your terminal does not switch between 80 and 132 columns you may specify 24x80.80, for example, to avoid a misleading display.
Other options are:
-V print the program version, and exit.
-f fontfile
specify a file containing a DRCS (soft character definition) string.
-l log test results to vttest.log.
-p use padding, e.g., for a VT100 connected to a high-speed line.
-s add time-delay in selected panning/scrolling options to show details.
-8 use 8-bit controls (this can be changed with a menu option).
