NAME
vttest - test VT100-type terminal
SYNOPSIS
vttest [options] [24x80.132]
DESCRIPTION
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.
OPTIONS
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:
-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.

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