Chapter 1 27
Introducing the TN3270 Emulation Program
Overview
International Language Support
The TN3270 emulation program provides the facility to communicate
with hosts using international language variants of EBCDIC. This
facility enables you to send and receive all the characters associated with
a selected host language, including those specific to that language. The
TN3270 emulation program supports both single-byte and double-byte
host languages.
Whether your terminal displays international characters depends on the
support for these characters provided by your HP-UX computer and its
terminals. Only screen Model 2 supports double-byte characters.
3270 Status Line
During a 3270 session, the bottom line of your screen contains a status
line that shows messages. These messages give the same information as
those on an IBM 3278 or 3279 display terminal; they provide real-time
information about the characteristics and activities of the session.
The way in which this status line information is displayed on the screen
depends on your terminal's hardware and software and on your TN3270
customization. The status line information can be displayed in one of the
following ways:
• Written to the terminal's status line (if the terminal supports this)
• Written to a spare line at the bottom of the screen (if the screen has
more lines than your 3270 screen model requires)
• Shared with the last line of the 3270 display (in which case you press
a key to switch between the status line and the last display line)
For more information, see Appendix B, “Status Line Information.”
You can also press a key to display a screen of help information about the
status line. This screen explains the value that appears in each field on
the status line of the current session.
Motif If you are using the Motif TN3270 emulation program with the Japanese
host language, an additional status line, the “Japanese extended status
line,” is displayed below the standard one, showing additional messages
that are specific to the Japanese language. The extended status line is
not supported in the character-based program.
