IBM 1483DSV User Manual

The following sections tell you how to enter Split Screen mode and use the split screen
enhancements.

To enter Split Screen mode, press and hold down the Alt key while you press the Dual
key. The display station remains in Split Screen mode until you run the Alt-Dual key
sequence again or go offline. While the display station is in Split Screen mode and is in
communication with the controller, such enhanced functions as top and bottom display,
mark/paste, and special key assignments are available.

When the display station is not in Split Screen mode, it operates like a standard 3270
display.

Split Screen mode permits a standard 1483 single-imaging device to simultaneously
display two host sessions. Because two or more sessions must be managed, one session
is selected as the active session and the other as the inactive or suspended session. The
active session is always displayed and, because the split screen 1483 can concurrently
display both the active and the suspended sessions, the active session is the session that
contains the cursor. For this reason, use either a block or a blinking cursor for Split
Screen mode.

The top session is displayed with 24 lines of Mod 2 data plus the status row information
with a separator line below the status row. The bottom session is displayed with 18 lines
of data with the status row information below those 18 lines.
