Fields

The Control screen lets you configure the following information:

  • Initial echo. Echo allows terminal input to be echoed back to the terminal by the computer as it is received. This field lets you turn initial echo on or off. The value entered takes effect whenever the terminal type is used. It occurs at speed sense or FOPEN time for the default terminal type or when the terminal type is changed through the FCONTROL intrinsic.

    NOTE: There are applications that depend on echo being off. For these applications to function correctly, the program needs to first select the terminal type file desired and then set echo.

  • Is form feed allowed in output data (Y,N). Replacement character for form feed. These fields let you specify whether form feed will be included in output data. If form feed is not included in output data, then you must supply a character that will replace the form feeds (FFs) in the data stream. Typically, you should enter LF.

  • System response to backspace. This field lets you configure a response to the backspace character. The responses and their meanings are displayed below the backspace response field.

    In all cases, when echo is enabled, a backspace is echoed to the terminal screen which might cause some action to the data on the terminal screen. An additional response from the system might be required for better cursor positioning.

    • 1 — nothing. This is the default and it causes the cursor to backup one space if echo is enabled but it does not erase the character.

    • 5 — erase character. This response is to output a space and a backspace character, which erases the character from the display.

      NOTE: If echo is disabled, then the selected response will not occur.

  • Is typeahead enabled? (Y,N). Typeahead allows the terminal user to continuously enter data without having to wait for the system to process the data and return the MPE prompt (:). This field lets you turn on or off typeahead by entering either Y or N.

  • Typeahead Echo Mode. The value entered here determines whether the input characters will be echoed to the terminal's screen once or twice.

    • 0 — Double echo. If 0 is entered, the HP 3000 will echo the characters twice to the terminal's screen.

    • 1 — Single echo. If 1 is entered, the HP 3000 will echo the characters once to the terminal's screen.
