TERMINF2

     1.  Give the known names of the terminal.

     2.  List and define the known capabilities.

     3.  Compile the newly created description entry.

     4.  Test the entry for correct operation.

TERMINF3

     The compiler for compiling terminfo entries is tic,

     and has the following syntax:

            tic  [-v]  file1 file2 ...

GO

 The terminfo database describes terminals by listing 

 a set of capabilities and describing how the terminal

 performs certain operations.  Each terminal description contains

 the names by which the terminal is known and a group of

 comma-separated fields describing the actions and capabilities

 of the terminal.

 All terminfo files are in the directories whose

 names are the first letter of the terminal names.

 For example the files for the terminals:

 vt52, vt220, videotrack, volkterm, etc., would be in the

 directory /usr/lib/terminfo/v.

 For details see above.

 Now you can tell where the programs  that address the screen, 

 including the CTI tutorials and vi, look to find the proper 

 control sequences for your terminal.

 Therefore, terminfo files provide terminal independence

 for UNIX applications!

 The procedure for building terminal description is

 as shown above.

 The terminal description entries are very similar to those

 used on the earlier versions of UNIX in the /etc/termcap

 file.  You must remember, however, that the terminfo

 entries are compiled.  A sample terminal definition file is

 shown above.

 These terminal definitions are used by the curses routines

 which provide high-level access to terminal control capabilities.

 It is important for one to understand the features of terminfo

 and how to build terminal definition files; however you should not use

 low level calls to access the terminal capabilities, but rather

 you should use the curses library for any terminal programming.

 For information on how to build terminfo entries, see the

 detailed description of terminfo in your manual!
