Creating Device Descriptions
The easiest way to create a new entry for a device is to find one that is
similar, modify it, and compile it using the tic utility. The tic
utility installs the new definition in the TERMINFO directory hierarchy.
You can change the location of the directory hierarchy by redefining the
TERMINFO environment variable.
You can test your description in small segments using VI. Keep in mind
that a unusual device may not be adequately described by TERMINFO or
adequately tested by VI.
A terminal can be defined as having certain capabilties that are
equivalent to those of another terminal. These capabilities are then
read from one terminal description into the other. The use capability
names the terminal from which to read the capabilities. Any capabilities
listed before the use string override those put in place by use. A
capability that should not be used in the terminal desciption can be
cancelled by typing an at sign (@) after the name of the capability. The
following example bases the definition of a VT-100 terminal without
automatic margins on a standard VT-100 terminal definition.
vt100-nam|VT100 without automatic margins,
am@, use=vt100,
A crude test for getting the right amount of padding for insert-line (if
not documented) is to comment out xon, edit a large file at 9600 baud
with VI, delete 16 or so lines from the middle of the screen, and press
the u key several times quickly. If the display becomes corrupted,
insert-line requires more padding.

Names of Capabilities
Capability names are normally kept to two to five characters and normally
comply with ANSI X3.64-1979. Each capability has a corresponding
variable name used in the program to access it; for example, the variable
defined for am is auto_left_margin.
The Boolean, number, and string capabilities are listed in the tables on
the following pages. Within these tables, each TERMINFO capability name
is listed, along with the equivalent termcap name, the variable name, and
a brief description. The #i symbol that sometimes appears in the
description section of the table refers to the ith parameter.
Additional tables sorted by variable name may be found in Table 3-21 ,
Table 3-22 , and Table 3-23 as a reference for programmers. Table
3-21 lists the capabilities by the Boolean variable name; Table 3-22
lists the capabilities by the numeric variable name, and Table 3-23
lists the capabilities by the string variable name.
