Configuring the PuTTY Telnet Client

PuTTY is a Windows PC telnet/ssh client that you can use to connect to the server where Meta RF is installed. Launch PuTTy from the Start menu. To run MetaRF from a PuTTY session, these settings must be changed:

  1. Select Session on the PuTTY Configuration screen. The Host Name should be set to point to your Meta RF server. Typically, the port is set to 23 for Telnet and 22 for SSH.
  2. Select Terminal > Keyboard, and then set these settings:
  3. The Backspace key:
    • Select Ctrl-H for Windows.
    • Select Ctrl-? for Linux.
  4. The Function keys and keypad: Select Xterm R6.
  5. Select Terminal > Bell, and then set these settings:
  6. Action to happen when a bell occurs: Select Beep using the PC speaker.
    • Meta RF uses the ASCII bell character when error messages are displayed. To support these sounds, you should use the PC speaker as the terminal bell since the setting Make default system alert sound may not work if the Windows default sound is off.
  7. Taskbar/caption indication on bell: Optionally, select Flashing.
  8. Control the bell overload behavior: Optionally, select Bell is temporarily disabled when over-used. If selected, specify these additional settings:

    • Over-use means this many bells

    • In this many seconds

    • Seconds of silence required

  9. Select Window > Appearance, and then select a relevant font and script that best matches the Meta RF user’s language. For example, a Chinese user may need a font and script-specific support for the Unicode characters needed by the language. We recommend FangSong (Chinese GB2312) font/script for the Chinese language.
  10. Select Window > Translation, and set these settings:
  11. Remote character set: Select UTF-8. Meta RF uses the universal UTF8 character set and PuTTY needs to use the same character set regardless of the O/S, system locale, or language.
  12. Select Treat CJK ambiguous characters as wide.
  13. Select Connection > Data, and set these settings:

    • For Linux platform, under

      Environment variables

      , specify

      HH_locale

      for variable and

      HH_device

      . HH_locale specifies the language of the login prompt and HH_device specifies the orientation of the device, landscape=8x40 and portrait=16x20.

      • You can also set this information in the user startup file, such as

        .profile

        ,

        .bash_profile

        , or .

        bashrc

        in the

        metarf.ini

        file. The startup file takes precedent over the PuTTY environment variable that takes precedence over the

        metarf.ini

        file setting.

    • For Windows platform, you must configure the parameters in Pragma or the

      metarf.ini

      file. Pragma environment variables in the user configuration override

      metarf.ini

      variables when they are configured in both places.

  14. Click Open to start the PuTTY session.
