TERMINFO terminal capabilities

When the INFORMIXTERM environment variable is set to terminfo, the runtime system will use the ncurses or curses library of the UNIX™ system to display and interact with the terminal device defined by the TERM environment variable.

Make sure that the Curses library is installed on your UNIX operating system. Check operating system installation requirements for more details.

The TERMINFO environment variable can be used to define a different terminal capabilities database as the default. If your UNIX system is properly configured, there is no need to set the TERMINFO environment variable.
