 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.

      -c commands
           replay commands recorded by the logging option.  Some keyboard
           and mouse input is required, depending on the tests, but
           otherwise menu selection and next-page responses are automated.

      -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.

      -u   suppress switch from UTF-8 mode on startup, and enable a third
           setting in the 7-bit/8-bit parsing test to allow for C2 controls
           as an alternate to 8-bit C1.

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

 ENVIRONMENT
      When vttest starts, it checks the locale (LC_ALL, etc.), to determine
      if the terminal uses UTF-8, and normally switches the terminal to
      ISO-8859 1.  Use the "-u" option to disable this switching, and
      provide some special cases where UTF-8 encoding is accepted.

      For example, the Unicode specification does not document its
      relationship to ECMA-48 (ISO 6429) beyond listing C0 and C1 codes
      which Unicode treats as whitespace.  The latter (i.e., NEL U+0085) is
      misleading because Unicode describes C1 controls only obliquely.  It
      goes into a little more detail regarding ECMA-35 (ISO 2022).  vttest
      allows for both the standard encoding of C1 (single byte) and the
      variant implied by Unicode, referred to here as C2 (two bytes) to
      distinguish the two encodings.
