Required and Recommended Functions
In order to use the ASCII interface, your terminal must have certain
requirements defined in the HP-UX computer's terminfo database. The
two types of functions to be defined in the terminfo database are
required and recommended.
Terminals without the required functions cannot be used with the menu
interface. (However, they can be used for other SNAplus2 functions such
as the command-line administration program or application programs
using the APIs provided with SNAplus2.) Terminals without the
recommended functions can be used with the menu interface, but these
functions make the screen interface easier to use.
The 3270 emulation program's default keyboard mapping (the mapping
between keystrokes on your terminal and the 3270 keys they represent)
assumes that your terminal's keyboard has all the required and
recommended keys. However, you can always remap a 3270 key to a
different keystroke if your terminal does not have the default key.
Any additional keys on your terminal should be included in the
terminfo database if you want to use them in the 3270 emulation
program to represent 3270 keys. For example, if you have the function
keys f9 - f24, you will probably want to ensure that those keys are defined
in the terminfo database for your terminal.
Required Functions
The following table contains the functions that must be defined in the
terminfo database. Also included are the capabilities SNAplus2 uses to
define each function:
