Configuring and Managing 3270 Terminal Emulation (TN3270) 18-11
Displaying and Customizing Keyboard Maps
Local> CHANGE TN3270 TERMINAL PC_100_DCA KEYMAP NEW_KEYS
You can carry out a similar process for terminal devices that use the VT220 keyboard
map—the other default map.
Local> CHANGE TN3270 TERMINAL PC_220_DCA KEYMAP VT220
Local> CHANGE TN3270 TERMINAL PC_220_DCA KEYMAP NEW_KEYS2
Customizing Server-Wide Keyboard Maps
After executing the CHANGE commands as shown in the Defining New Server-Wide
Terminal Types and Keyboard Maps section in this chapter, you can customize the
individual keymapping assignments in the new keyboard map NEW_KEYS. The goal
is to have key assignments that fit the needs of the port users who can select the
terminal type that goes with a new keyboard map.
The following command changes the keymapping assignment for the TN3270 function
CLEAR. Instead of the default VT100 keymapping EXT ENTER, the manager assigns
the CLEAR function to Ctrl/W.
Local> CHANGE TN3270 KEYMAP NEW_KEYS CLEAR <CTRL/W>
In a display, the customized keymapping assignment is marked with an asterisk (*).
The privileged user can show the new keymapping with this command:
Local> SHOW TN3270 KEYMAP NEW_KEYS
Rules for Customizing Keyboard Maps
The following rules apply to customizing keyboard maps:
• You can assign each 3270 function to only one ASCII key sequence.
• If you attempt to assign a 3720 function to an ASCII key sequence that is already
in use, the access server:
— Issues a warning message.
— Assigns the requested key definition.
— Assigns the 3270 function previously assigned to this sequence to NONE.
• You cannot assign an ASCII key sequence that is a subset of a key sequence
already assigned to a 3270 function. For example, the assignment of “KPDOT” to
a 3270 function is disallowed if “KPDOT F20” is already assigned to a 3270
function.
