Step 5. Logging On To The Sna Host; 3708 Logon Indication Screen (C4) - IBM 3708 End-User Reference

Step 5. Logging on to the SNA Host
If the 3708 Logon Indication Screen (C4) is configured, the following screen is
displayed.

Figure 1-6. 3708 Logon Indication Screen (C4)
Note: The logon indication screen may be immediately followed by a screen from
your host, depending on your installation.
After the logon indication screen (C4) is displayed (or, if no logon screens are being
used), anything entered on the screen is sent to the host. (Four
"#"
characters
(####)
followed by an ENTER key can still be used to terminate your connection.)
Normally at this time, you would type in a logon request, or your host might log the
terminal on automatically. In both cases, the host sends a command to the 3708 to
start the session. The command contains information that tells the 3708 what mode
is to be used for the session: line-by-line, or full-screen.T4
See your system administrator to determine which mode you are using. Refer to
Chapter 3, "Operating in Line-by-Line and ASCII Pass-through Modes" for
information on how to operate your device when in the line-by-line mode, and to
Chapter 2, "Operating in Full-Screen Mode" for information on operations in
full-screen mode.
T4
Technical Note: To initiate the SNA session, the host sends a BIND. The Bind contains an LU-type field that tells
the 3708 what mode to use: LU type 1 is specified for a line-by-line session, and LU type 2 is used for arull-screen
session.
