vttest(1) 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, 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).
