IBM 1483DSV manual Operation, Entering Split Screen Mode, Active and Suspended Screens

Operating the Split Screen Feature

Operation

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

Entering Split Screen Mode

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.

Active and Suspended Screens

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.
