Use this command to change the keyboard mapping for the current terminal emulation session. This command displays the Keyboard pane of the Session Setup dialog box. The Keyboard pane contains the following options.


Keyboard Map NameA default keyboard map is provided for each terminal type supported by TN3270 Plus. You may modify the default keyboard map or build your own customized keyboard map(s) by changing the default keyboard map and saving it with a new name. To modify an existing keyboard map or to create a new keyboard map, click the Configure... button to display the Keyboard Map Setup dialog box. Once you have created a customized keyboard map, you can select it from the Keyboard Map Name drop-down list box.


Type AheadThe Buffer Size edit box contains the size of the type-ahead buffer. You may increase or decrease the size of the type-ahead buffer by changing this value. Check the Disable check box to disable the type-ahead buffer support.


Destructive BackspaceCheck this box to enable destructive backspace. With destructive backspace enabled, the backspace key will delete a character as it moves the cursor over it. With destructive backspace disabled, the backspace key will not delete a character; it will simply move the cursor.


Respect numeric fieldsCheck this box to respect numeric fields. This means that only numeric characters can be typed into 3270 screen fields with the numeric field attribute turned on. When this option is on, you can override the numeric field requirement by holding down the shift key and entering non-numeric characters. (3270 sessions only).        


Lock keyboard on operator errorCheck this box if you want the keyboard locked after a data entry error. Remove the check to prevent locking of the keyboard. The default is unchecked (3270 and 5250 sessions only).


Suppress alarm on operator errorCheck this box to suppress the beep if an operator types into a protected field or presses an invalid keyboard combination. The default is unchecked (3270 and 5250 sessions only).


Typematic AID keysCheck this box to make all AID generating keys typematic (repeating). However, the key will only be repeated when the host unlocks the keyboard. This is to prevent the type-ahead buffer from filling up with AID keys while the host is processing the last key (3270 and 5250 sessions only).
Don't reset insert mode on Enter/AID keyCheck this box to prevent insert mode from being reset (turned off) after the Enter key or an AID key is pressed (3270 and 5250 sessions only).
Upper-case inputCheck this box to make all keyboard input appear in upper case regardless of the CAPS lock setting.
Disable application cursor keys modeCheck this box to disable sending alternate escape sequences for the normal arrow keys. This option is rarely used. (VT100, VT220 and ANSI sessions only).
Disable application keypad modeCheck this box to to disable sending alternate escape sequences for the keypad keys. For example, use this option if the keypad keys do not work correctly with the vi editor. This option is rarely used. (VT100, VT220 and ANSI sessions only).
