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.


You can specify the screen geometry in the form [24x80.132], i.e.,

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:


print the program version, and exit.

-f fontfile

specify a file containing a DRCS (soft character definition) string.


log test results to vttest.log.


use padding, e.g., for a VT100 connected to a high-speed line.


show only the most recent part of a continuous response, e.g., any-event mouse tests, to improve readability of the test.


add time-delay in selected panning/scrolling options to show details.


use 8-bit controls (this can be changed with a menu option).

Modified by Thomas Dickey from June 1996, to support nonstandard screen geometry, VT220-VT520, ISO color and xterm-specific tests.
