Start a 3270 Telnet client session

This topic explains how you can start a Telnet client session using 3270 emulation.

When the Telnet client negotiates 327x workstation support with the remote Telnet server application, the system activates the 3270 full-screen mode. Telnet client negotiates 3270 full-screen support with any Telnet server application that supports 3270 full-screen (rather than 5250) applications. The remote system application controls your display station. You receive the same displays and enter data the same way as you will for other 3270 devices locally attached to the remote system.

You need to start the Telnet server on the remote system (the server system that you want to connect to using Telnet).

You should know the name or Internet address of the remote system with which you want to start the Telnet session. To display the Internet addresses and host names, complete the following steps:

  1. Start iSeries™ Navigator and expand your iSeries server > Network.
  2. Right-click TCP/IP Configuration and click Host Table to display the Internet addresses and host names.
  1. Type the STRTCPTELN command, or type TELNET at the command line and press Enter.
  2. Type the name of the remote system. If you want to use the optional parameters, press F10, otherwise press Enter.

    If you type *INTNETADR for the Remote system name and press Enter, the server prompts you for the Internet address field.

  3. Type the Internet address of the remote system. To use the optional parameters, press F10, otherwise press Enter. The display shows optional parameter values and the Internet address information.
  4. To use the default parameter values, press Enter. The connection to the Telnet server will start.
  5. During a 3270 full-screen mode session, the following optional parameters are also applicable:
    • Timeout wait for host (INZWAIT)
    • Keyboard language type (KBDTYPE)
    • Page up (roll down) key (PAGEUP)
    • Page down (roll up) key (PAGEDOWN)
    • Cursor select key (CSRSLT)
    • Outgoing 3270 translation table (TBL3270OUT)
    • Incoming 3270 translation table (TBL3270IN)
    • Numeric lock keyboard (NUMLCK)
    • Change how nulls are handled (NULLS)
    • Port number of the remote host server application (PORT)

The next display is the signon display for the remote system.
