Establishing Multipie Host Connections
Session Indicators
The logical terminal (LT) identifier allows you to differentiate between multiple
sessions. The LT identifier is located in the fourth column of the lower left corner
of your screen. (See Figure 1-1 for an illustration of a typical screen.) Each time
you use the Change-Screen key sequence, the indicator reflects which session is
active. The following list shows the session number and its related LT identifier.

X.25 host communication protocol.

If you turn on the terminal and only one session is defined, the LT indicator
position remains blank. If you turn on the terminal and the controller cannot
currently support multiple sessions, the indicator position contains LT-X. This is a
signal that the controller may have a configuration error. You should notify your
system administrator if this happens.
The following sections describe additional information that may appear in the OIA
or status line on your terminal.
