Using the Display As a Viewport
The TRAKKER 2425 terminal display shows 16 lines by 20 characters of data
at one time. In terminal emulation (TE) applications, the terminal’s display
may show only part of each 25 line by 80 character screen that appears on a
full-size terminal. You can use the terminal display as a viewport to move
around and see the entire 25 x 80 screen.
The viewport lets you view screens and enter data by showing the part of
the screen you are using. When you are using TE, the viewport
automatically moves to the cursor when there is data entry from the host
computer or the terminal. You can configure the viewport for your TE
applications to:
• Follow the cursor
• Center the viewport around the cursor
For help on configuring the TE viewport options, see Chapter 5, “Running
Applications.”
The first time you turn the terminal on, it displays the upper left corner of a
full-size terminal screen. This is the viewport’s home position. A screen or
application that displays more than 16 lines by 20 characters of data at one
time has data in the unseen area of the display. When you move the cursor
or viewport out of the home position (upper left corner), the Viewport icon
displays until the viewport is returned to its home position.
