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.

  • To run a given menu-item, you must enter its number.
  • Menu items start at zero; this is the “Exit” item in almost all cases.
  • You can run all menu-items (for a given level) by entering an asterisk, i.e, “*'.
  • You can force a repaint of the menu items by entering “?”.
  • 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.,

  • 24 lines,
  • 80 minimum columns, and
  • 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:

print the program version, and exit.
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.
-8
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.
