VT102.

------

VT100 is a video terminal that was made by Digital Equipment Corporation (DEC). It was introduced in

August 1978. Its detailed attributes became the de facto standard for terminal emulators.

The control sequences used by the VT100 family are based on the ANSI X3.64 standard, later ECMA-48

and ISO/IEC 6429.

The VT101 and VT102 were cost-reduced non-expandable follow-on products, with the VT102 including

the AVO and serial printer port options of the VT100.

In 1983, the VT100 was replaced by the more-powerful VT200 series terminals such as the VT220.

luit.

-----

Luit is a filter that can be run between an arbitrary application and a UTF-8

terminal emulator. It will convert application output from the locale's

encoding into UTF-8, and convert terminal input from UTF-8 into the locale's

encoding.

Example::

  $ luit -encoding 'ISO 8859-1' emacs -nw
