term(5) DG/UX R4.11MU05 term(5)
NAME
term - conventional names for terminals
DESCRIPTION
Terminal names are maintained as part of the shell environment in the
environment variable TERM [see sh(1), csh(1), profile(4), and
environ(5)]. These names are used by certain commands [for example,
man(1), tabs(1), tput(1), and vi(1)] and certain functions [for
examples, see curses(3X) and termcap(3X)].
Files under /usr/share/lib/terminfo are used to name terminals and
describe their capabilities. These files are in the format described
in terminfo(4). To print a source description for a terminal term,
use the following command:
infocmp -I term
[See infocmp(1M) for more information.]
Entries in TERMINFO source files consist of a number of comma-
separated fields. White space after each comma is ignored. The
first line of each terminal description in the TERMINFO database
gives the names by which TERMINFO knows the terminal, separated by
bar (|) characters. The first name given is the most common
abbreviation for the terminal. This is the preferred one to use to
set the environment variable TERM; see profile(4). The last name
given should be a long name fully identifying the terminal. All
others are understood as synonyms for the terminal name. All names
but the last should contain no blanks and should be unique in the
first 14 characters; the last name may contain blanks for
readability.
Terminal names (except for the last, verbose entry) should be chosen
using the following conventions. Select a root name based on the
particular piece of hardware making up the terminal; for example, for
the Data General D463 terminal, d463. This name should not contain
hyphens, except that synonyms may be chosen that do not conflict with
other names. Up to 8 characters, chosen from the set a through z and
0 through 9, make up a basic terminal name. Names should generally
be based on original vendors rather than local distributors. A
terminal acquired from one vendor should not have more than one
distinct basic name. Terminal sub-models, operational modes of the
hardware, or user preferences should be indicated by appending a
hyphen and an indicator of the mode. Thus, a Data General D463
terminal in 132 column mode is d463-w. The following suffixes should
be used where possible:
Suffix Meaning Example
-------------------------------------------------------------
-w Wide mode (more than 80 columns) d463-w
-am With automatic margins (usual default) vt100-am
-nam Without automatic margins vt100-nam
-n n number of lines on the screen aaa-60
-na No arrow keys (leave them in local) c100-na
-np n number of pages of memory c100-4p
-rv Reverse video att4415-rv
To avoid conflicts with the naming conventions used in describing the
different modes of a terminal (e.g., -w), it is recommended that a
terminal's root name not contain hyphens. Further, it is good
practice to make all terminal names used in the TERMINFO database
unique. Terminal entries that are present only for inclusion in
other entries via the use= facilities should have a `+' in their
name, as in 4415+nl.
The most useful known terminal names are summarized in the table
below. For a complete list, enter the following command:

Commands whose behavior depends on the type of terminal should accept
arguments of the form -Tterm where term is one of the names given
above; if no such argument is present, such commands should obtain
the terminal type from the environment variable TERM, which, in turn,
should contain term.

NOTES
Not all programs follow the above naming conventions.
The following line discipline stty(1) settings are recommended for
Data General terminals:
nl -tabs -istrip for eight-bit ANSI and DG modes.
nl -tabs for seven-bit ANSI and DG modes.
-nl tabs for VT100 mode.
-nl tabs -istrip for VT220, VT320, and DG-UNIX modes.
-nl -tabs -istrip for eight-bit ANSI-LF mode.
-nl -tabs for seven-bit ANSI-LF mode.
In addition to supporting the Data General D216 terminal in its VT100
mode, the d216 entry supports the D216+ terminal in its VT100 mode.
The vt100 entry can also be used with these terminals; it makes the
numeric keypad work as an additional set of function keys (but of
course prevents the keypad from being used for data entry).
In addition to supporting the Data General D412 and D462 terminals in
their VT220 modes, the d412 and d462 entries support the D412+ and
D462+ terminals in their VT320 modes. The vt220 entry can also be
used with these terminals; it maps the function keys so that they are
more suitable for a touch-typist familiar with a VT220/VT320 keyboard
(but then the function key labels do not match the keys' effects).
The default entries for the xterm terminal emulator, xterm and
xterms, are compatible with the vt100 entry. They make the numeric
keypad work as an additional set of function keys, but do not take
advantage of the large number of function keys found on modern
keyboards (such as the PC-style keyboard used on AViiON
workstations). Additional entries, xterm-fk and xterms-fk, are
provided to enable use of these function keys and to allow data entry
from the keypad; they are usable with any keyboard that has modern
function keys. Two more entries, xterm-dg and xterms-dg, are
provided; they are similar to xterm-fk and xterms-fk, but match the
keys and layout of an AViiON keyboard exactly.
The d230c terminal entry supports both seven-bit and eight-bit
character sizes in a single entry. Separate entries are required for
other DG terminals in ANSI mode, one to support each character size.
Support for Data General terminals in DG mode is limited because this
mode does not in general work well on UNIX systems. The problem is
that the ANSI standard backspace character (Ctrl-H) causes the cursor
to ``home'' to the upper-left corner of a DG terminal in DG mode.
This behavior is incompatible with the way characters and lines are
erased from the screen by the tty(7) driver; the cursor will go to
the home position whenever the erase key is pressed. This problem
can be partially avoided by using editread(5) or by using stty(1) to
turn off echoing for the ERASE and KILL characters.
The 6053, D200, D400, and D450 terminals provide only DG mode.
International Notes
The Data General D216, D216E, D216+, and D216E+ terminals do not
support eight-bit characters in their VT100 modes.
The d412, d413, d462, and d463 entries support eight-bit characters
but require that the terminal be set for ``seven-bit control''
sequences.
Data General terminals in (eight-bit) ANSI, DG-UNIX, and DG modes use
the proprietary ``DG International'' code set, instead of an standard
code set such as ISO 8859-1. Data General terminals in VT220 and
VT320 modes use the ``DEC Multinational'' code set, which is a
compatible subset of ISO 8859-1.
The 6053, D200, D210, D214, D400, and D450 terminals do not support
eight-bit characters at all.
