254Definition of Key Codes

Syntax Description

When using the Telnet applet available under the Portal’s Advanced tab, there is an option to specify a keymap URL that points to a key code definition file. If your application uses a different keyboard layout than the standard VT320, a key code definition file can be created and uploaded to the keymap URL. This appendix shows how to create the key code definition file. Almost all special keys can be defined according to the following syntax rule:

[SCA] KEY=STRING

The characters enclosed in [ and ] are optional. Only one of the characters ’S’ (SHIFT), ’C’ (CTRL) or ’A’ (ALT) may appear before KEY, which is a textual representation of the key you wish to redefine (F1, PGUP and so on.).

The new STRING to be sent when pressing the key should come after the equals character (=). Hash marks (#) in the file declare the line as a comment and will be ignored. The following examples explains the syntax in more detail:

Send the string "test" when pressing the F1 key:

F1 = test

On pressing Control + PGUP, send the string "pgup pressed":

CPGUP = pgup pressed

Redefine the key Alt + F12 to send an escape character:

AF12 = \\e

As can be seen, the string may contain special characters which may be escaped using the backslash (\).

Allowed Special Characters

The following table includes allowed special characters:

Note: For some of the escape codes you need two backslashes, as these are specific javassh definitions not known by the Java Property mechanism.
