This chapter provides information on how to run the IRIS 3270 Emulator software on an ASCII terminal. The IRIS 3270 Emulator supports three ASCII terminal types: VT100, iris-ansi, and xterm terminals. With an ASCII terminal, the IRIS 3270 Emulator supports only IBM 3278 Model 2 terminal emulation. You can access a 3270 terminal emulation session by remotely logging in to a workstation running the IRIS 3270 Emulator. ASCII terminals can support only one active session at a time.
This section explains how to run an IRIS 3270 Emulator session by establishing an active link to the host, starting a session, and operating the ASCII terminal as a 3278 terminal.
During a 3270 emulator session, many of the standard keyboard characters are assigned added functions needed in the 3270 environment. You can make use of these functions by pressing keys in various combinations. To see an online list of key combinations for ASCII terminals, press <Ctrl-e> from the 3270 emulation window.
Table 3-1 shows the IBM 3270 keys and the equivalent VT100, iris-ansi, and xterm key sequences.

Press <ESC P> to save your current screen image as described in Chapter 2, “Using the IRIS 3270 Emulator.”
The 3270 terminal status line displays operational status information from the host and the 3270 system about the validity of session-specific operations.
Refer to Appendix C, “3278 Status Line Codes and Messages” for descriptions of the most commonly encountered status line codes and messages and the equivalent IBM 3278 graphic symbols for each message. If you encounter an error message not described in Appendix C, press the <RESET> function key and retry the operation. If this attempt is unsuccessful, refer the problem to the system administrator.
To display the status line, press the <SWAP25> key, which is <Ctrl-a> on the IRIS keyboard. The <SWAP25> key is a toggle. The first time you press it, it displays the status line, overwriting line 24. When you press <SWAP25> a second time, the status line disappears and line 24 is displayed again. Normally, the status line is not shown. Use <SWAP25> to check the status of your session if the host is taking an unusually long amount of time to respond and the status line is not currently displayed.
To activate the IRISXFR Set Up screen, press <Ctrl-f>. Data entry instructions for each field of the menu are displayed in the help area. Once you have initiated the transfer, the IRISXFR Transfer Summary appears. For complete information about IRISXFR, see Chapter 4, “Transferring Files.”
To activate the IND$FILE Set Up screen, press <Ctrl-b>. Data entry instructions for each field are displayed in the help area. Once you have initiated the transfer, the IND$FILE Transfer Summary appears. For complete information about IND$FILE, see Chapter 4, “Transferring Files.”
