Workstation Configurator — Screen and Field Definition
Control
• 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.
