vttest - test VT100-type terminal
vttest [options] [24x80.132]
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
- You can run all menu-items (for a given level) by entering an asterisk,
- 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, 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:
- -f file
- 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.
- add time-delay in selected panning/scrolling options to show details.
- use 8-bit controls (this can be changed with a menu option).

geometry, VT220-VT520, ISO color and xterm-specific tests.
