Using Your 3270 Terminal As An Ibm 3101 - IBM 3174 Reference Manual

Using Your 3270 Terminal as an IBM 3101
You can use the Connection Menu to request a different host session or to check
the status of a host. The Connection Menu contains a list of all the possible host
destinations and provides information you need to connect to a host. If you are
authorized, you can select a destination from this menu.
The following list describes the messages that show the status of the host:
Status Meaning
UP The host is active and available.
? Host status cannot be determined. A request to establish a session
with the host either succeeds or provides more detailed status
information.
DOWN The host is inactive, or all the ports that can access it are broken.
BUSY The host is active, but all the ports to it are in use.
DIAL The host is accessed through a switched port. A request to connect to
the host either succeeds or provides more detailed status information.
You can update the Connection Menu by pressing Enter. This signals the
controller to refresh the status column of the menu.
The following list describes the functions of the PF keys:
PF Keys Function
PF3 Returns you to the session you left. On an SNA controller, if you press
PF3 without connecting to a new host, the previously connected host
session resumes. On a non-SNA controller, the previously connected
ASCII host session resumes. If the previous connection was to the 3270
host, the connection is re-established. However, it may be necessary
for you to log on again.
PF12 Breaks the active session connection between the 3174 and the host if
you are connected to an ASCII host. This releases the host port for
other users and, if you are using a dial connection, disconnects the
switched connection, ending telephone charges. All other background
sessions are not affected.
You can get to a host by returning to the Connection Menu and typing in the
number or name of the host to which you want to connect. You can return to the
Connection Menu by using the extension mode or Extended Select key and then
pressing the Connection Menu key. See Figure 1-2 on page 1-8 through
Figure 1-4 on page 1-9 for these keys.
Using Your 3270 Terminal as an IBM 3101
The 3270 terminal operating as a 3101 only operates in character mode. In
character mode, all keystrokes are processed by the host before being echoed
back and displayed. Block mode is not supported. For more information about
actual 3101 operation, refer to the IBM 3101 Display Terminal Description.
