In this mode, the 1920 character screen format (24 lines x 80 characters) is
available for your display station. The following figure shows the 1920 character

Two-Display Mode Operation
In two-display mode, your display station has two display station addresses and
works as two display stations. The screen format is the same as that for
one-display mode.
Your display screen can interact with the host system using either one of logical
display station 1 or 2, but only one at a time can be used. The display of the
data from one logical display station can be switched to the other one by
pressing the Jump key. See the figure shown below.
