Controlling 3270 Emulation
Controlling Display Sessions
TN3270E
Session is communicating with the host TN3270
program using data messages in TN3270E format. This
format uses a 5-byte header, various data types, and
TELNET END-OF-RECORD (EOR).
TN3287
Session is communicating with the host TN3270
program using data messages in TN3287 format. This
format uses one zero-byte prefix for LU type 1 or LU
type 3 data and TELNET END-OF-RECORD (EOR).
Host_application_name
Session is communicating with the named host
application. This name is shown if it is available from
the BIND image exchanged during session activation.
If the BIND image is not available, either the value
TN3270 or TN3270E is shown.
The Control Display Sessions dialog box provides the following push
buttons:
<Make Current>
Choose this to make the highlighted session current, so
that it is the session you go to first when you begin or
resume 3270 emulation. You can make a session
current only if it is enabled and if its screen model is
one that your terminal can display. If you try to make a
disabled session current, a message box warns you that
you cannot. In that case, acknowledge the message by
choosing <Exit Message> in the message box and
then enable the session before making it current. For
more information about message boxes, see “Message
Boxes”. For more information about enabling sessions
and current sessions, see “Enabling a Display Session”
and “Making a Session Current”.
<Change Status>
Choose this to enable a disabled session or to disable
an enabled or active session. An active session is one
that is communicating with the host. In the Control
Display Sessions dialog box, an active session's status
appears as SSCP or TN3270. For more information, see
“Enabling a Display Session”.
