Define Your Terminal (Linux)
To define your terminal in Linux, select the appropriate command for your shell.
TERM_INGRES=termname
export TERM_INGRES
where
termname is the designation for your terminal type, as listed in
Terminal Names.
For example, if you have a VT100 terminal, and you want to be able to use the arrow keys as cursor movement keys and the keypad keys as definable function keys, the list under Terminal Names tells you that vt100i is the proper designation. To define your terminal accordingly to Ingres, enter one of the following commands:
TERM_INGRES=vt100i
export TERM_INGRES
Thereafter, you can use the VT100 default assignment of keys for cursor movement and executing forms commands in Ingres.
The vt100nk is another terminal designation available for VT100 terminals. This terminal designation is particularly suited to applications that require use of the keypad for numeric input. This designation gives the user access to the arrow keys and the top four function keys on the numeric keypad. The other keys on the keypad are available for numeric input.
If your Linux system provides full support for VT220 terminals, you can define a VT220 terminal as vt220 and use the VT220 keystrokes. Some Linux systems do not provide full support for VT220 terminals. In this case, you must set a VT220 terminal to emulate a VT100, using the VT100 keystrokes, as discussed previously.
