vi Overview
The TN5250 Connection
Guide Format Conventions
To operate TN5250 emulation, you must connect to an AS/400 server operating with OS/400 V ersion 1, release level 3.0 or higher . Additionally , you must be operating the emulator across a TCP/IP network, using an IBM 8209 or equivalent TCP/IP attachment. When you use TN5250 terminal emulation, you are communicating directly with the AS/400 server. This communication is accomplished with the IBM AS/400 system internet protocol. Figure 1 shows the TN5250 connection related to a terminal.

Sessions
If you connect to a TN5250 server using a definition that contains an IP address, the emulator will open up an initial TN5250 ses sio n (emulator­opened session) using that IP address. That session will be placed in the Sessions list in the Sessions menu, as the initial open session (see Chapter 2, “The Menu System,” for more information).
If you try to connect to a server using a definition that does not contain an IP address, you will not connect. Instead, the emulator will display the TN5250 menu system, allowing you to create a session (user-opened session). Once a session is created, you can then connect and run your session.
A session must be opened to use TN5250 terminal emulation. This section discusses both emulator-opened sessions and user-opened sessions.

TypeAhead Buffering
Cmd T ab Alt o
Shift Tab Alt q
none
none
Applications such as data processing and word processing programs normally accept keystrokes as you enter information. However, these applications can lock your keyb oard when data i s being pro cessed. When a k ey boa rd locks, the II (Input Inhibited) indicator appears on the status line (see Appendix A). Keystrokes that you enter when the keyboard is locked (typing ahead) are not executed as you enter them.
To avoid reentering keystrokes, you can use the emulator’s TypeAhead Buffering (a terminal default). TypeAhead Buffering allows you to store additional keystrokes temporarily. When your keyboard unlocks, all stored keystrokes are automatically sent to the host and appear on the screen.
The TypeAhead key sequence is found in Keyboard Mapping/Local Function Keys (Alt :).
If you are operating your terminal in a data processing mode, keyboard buffering is normally inactive. If you are operating your terminal in a word processing mode, keyboard buffering is normally active.
Locked Keyboard
The system request, Alt Prtsc, and the error reset Ctrl (left), key sequences allow you to interrupt the keyboard’s locked state:
◆ Alt Prtsc
This is the system request key sequence. When you press this, the keyboard buffer is cleared and the terminal displays the System Request screen. The host will then process keystrokes normally, until you exit this screen by pressing either
Ctrl (right) key, or the Alt Prtsc key sequence.
Additional keystrokes are then stored in the keyboard buffer as needed.
◆ Ctrl
(left)
This is the error reset key. When you press this, the keyboard buffer is cleared and the buffer full mode is reset. Then your session returns, and keystrokes are processed normally. If keyboard buffering is active, keystrokes are stored as needed.

Error Messa ges
This section describes the error messages that might disp lay on your terminal screen during a TN5250 session. These error messages are grouped into three categories:
◆
Telnet errors
◆
TN5250 internal errors
◆

Telnet errors are generated by Telnet communications software within a TN5250 terminal. These errors are related to initialization, start up, or connections during a session. They are normally due to operator error, incorrect command syntax, or network failures, and can usually be corrected by the system administrator. Table A-1 lists Telnet error messages.
