/****************************************************************************
Skeleton driver for ADM 11 and related terminals by Lear Siegler, Inc.
* ADM 11 (June 1983): LSI's first terminal to use the "High Touch"
enclosure shared by the rest of its family and other LSI terminals.
Its detachable typewriter-style keyboard has only 4 function keys
(8 with shifting). Display is one 24x80 page plus a status line.
Font supports "business graphics" as well as ASCII characters.
* ADM 12 (March 1984): Expanded version of ADM 11 implementing block
mode and many more editing functions. 2 pages of text are available
in 80x24 mode, and there are also 80x48 and 158x24 modes.
* ADM 11G & ADM 12G (March 1984): ADM 11 and ADM 12 enhanced with
Tektronix Plot 10-like graphics.
* ADM 1178 (March 1984): Emulates the keyboard and communications of the
IBM 3278, though an external protocol converter is also required for
network compatibility.
* ADM 1278 (March 1984): Block mode version of the ADM 1178.
* ADM 12plus (February 1985): Later version of the ADM 12, with 132-
column and horizontal split display options. Up to 4 pages of display
memory are supported.
* ADM 11plus (June 1985): Later version of ADM 11 with more function
keys and character and line insertion/deletion.
