5.1.7 Set keyboard options

You can set the following keyboard options:

3270 keyboard options

  • Typeahead

    When this option is selected, Host Access for the Cloud buffers the characters that you type in the terminal window. Typeahead allows you to keep typing after you send data to the host. Without typeahead, characters you type are ignored until the host is ready for more data.

  • Word wrap

    When this option is selected, word wrap functionality is enabled within a multi-line, unprotected field. In word wrap mode, some of the blank spaces between words are replaced by line breaks so that each line is visible in the terminal window and can be read without horizontal scrolling.

  • Attention key sends

    Specifies what is sent when the ATTN key is pressed. The options are Telnet break, Abort output, and Interrupt process.

5250 keyboard options

  • Typeahead

    When this option is selected, Host Access for the Cloud buffers the characters that you type in the terminal window. Typeahead allows you to keep typing after you send data to the host. Without typeahead, characters you type are ignored until the host is ready for more data.

  • Error auto reset

    When selected, the next key pressed after a keyboard error clears the error, restores the previous error line data, and attempts to execute the keystroke as follows:

    • If the cursor is in a valid input field and the key is a data key, the data is entered there if it is valid data for that field (for example, a numeric character in an input field that only accepts numbers).

    • If the cursor is in a valid input field and the key is a function key, the key operation is executed.

    • If the current cursor position is not in a valid input field and the key is a data key, the cursor is moved to the next valid input field and the data is entered there if it is valid data for that field.

    • If the current cursor position is not in a valid input field and the key is a function key, the cursor is moved to the next valid input field and the key is ignored.

    • If the current screen contains no valid input fields, you'll see an error message with each keystroke you press, and no keystrokes are executed

    When cleared, you must press Reset to clear the error message from the error line before you can resume data entry.

    By default, this option is not selected.

  • Waive field checks for PF key

    Select this option to allow PF keys to be sent to the host from restricted fields. This option is cleared by default.

VT keyboard options

  • Backspace sends

    Configures the function that the Backspace key sends. On the VT terminal keyboard the back arrow key (<x) is configurable: it can send either a delete (ASCII 127) or a backspace (ASCII 8) character.

  • Local echo (VT)

    This option causes each character typed at the keyboard to be displayed on the screen. This option is cleared by default, because most hosts echo back received characters.

  • Cursor keys

    Controls the characters that the four arrow keys (on both the numeric and editing keypad) transmit. This setting is typically set by the host. In general, you should keep this set to Normal.

    If the arrow keys aren’t working properly, it may mean that this option remained incorrectly set to Application when a host program terminated abnormally. Changing this setting back to Normal should fix the problem with the arrow keys.

  • Keypad

    Controls the characters that the numeric keypad keys transmit. This setting is typically set by the host. In general, you should keep this set to Numeric.

    If the number or PF keys aren’t working properly, it may mean that this option was incorrectly left set to Application when a host program terminated abnormally. Changing this setting back to Numeric should fix the numeric keypad.

T27 keyboard options

  • Enable lower case (T27)

    Enables lower case, as well as upper case letters to be displayed on the screen. Default. If this is option is disabled only upper case letters will display.
