Step 5: Assigning Control

Figure 2-4 Control Screen

1. Verify that the cursor is in the Initial echo (ON,OFF) field. Echo allows terminal input to be echoed back to the terminal screen by the computer as the input is received.

2. Type to enable initial echo. Type OFF to disable initial echo.

1. Press the [Tab] key to move the cursor to the Form feed allowed in output carriage control (Y/N) field. This character is usually contained in the carriage control sent to the hard copy device. Some hard copy devices will not accept the form feed character.

2. Type Y if the form feed character should be sent to the hard copy device.

3. If the hard copy device will not accept the form feed character, type N. Verify that the cursor is in the Replacement character for form feed field. Enter the replacement character for form feed, usually LF.

1. Press the [Tab] key to move the cursor to the System response to backspace field. When echo is enabled, a backspace is sent to the terminal which might cause some action on the terminal's screen. An additional response might be required from the system for better cursor positioning.

2. Type 1 to back the cursor up one space, but entering 1 will not erase the character.

3. Enter 5 to back the cursor up one space and erase the character.

1. Press the [Tab] key to move the cursor to the Is typeahead enabled (Y,N) field. 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 (:).

2. Type Y to turn typeahead on. Type N to turn typeahead off.

1. Press the [Tab] key to move the cursor to the Typeahead Echo Mode field. The value entered here determines whether the input characters will be echoed to the terminal's screen once or twice.

2. Type 0 if the input characters should be echoed to the terminal's screen twice. Type 1 if the input characters should be echoed to the terminal's screen once.
