COMMUNICATION MODES
Chapter 3
The data area of the screen is the portion of a page of display
memory that can be viewed at anyone time. The default data
area is 24 data lines. The default page length is also 24 lines,
allowing you to see an entire page at a time on the screen. You
can set the Lines and Page Length setup parameters for other
combinations of data lines and page length.
Figure 3-2 shows a 24-line data area in a 24-line and 48-line

Four modes of communication are possible between the terminal
and the computer: full duplex, half duplex, block, and
half-duplex block. Figure 3-3 shows how the terminal handles
data in these communication modes.

Note Half-duplex mode should not be selected unless
required-characters will display twice if the host also echoes data
back to the screen.
