Introducing the TN3270 Emulation Program
Overview
Overview
The TN3270 emulation program gives you access to most of the standard
features of an IBM 3270 Information Display System (IDS) terminal,
such as extended attribute byte (EAB) support for color and extended
highlighting. Some of these features are available only if your HP-UX
computer and your terminal support them. For more information about
required hardware and software, refer to the HP-UX TN3270
Administrators Guide.
In addition, the TN3270 emulation program provides file transfer, local
copy, and keystroke record/replay capabilities and enables you to develop
and run High-Level Language Application Programming Interface
(HLLAPI) programs.
Support of TN3270 Features
The TN3270 product supports both the standard TN3270 features and
the extended TN3270E features that are described in the Internet
Request for Comments (RFCs) listed in “Related Publications”. TN3270E
supports all the standard TN3270 features and the following additional
features:
• LU type 1 and LU type 3 printing
• Access to specific display and printer LUs
• Access to printer LUs associated with display LUs
• Access to the SSCP-LU session
• Support for the ATTN and SYSREQ keys
• Negotiation of which enhancements to use on each connection.
The TN3270 product does not support the features described in Internet
RFC 1205: Telnet 5250.
The TN3270 product can connect directly to either a host computer that
supports TN3270 access over TCP/IP or to a communications product
that provides the TN server function. The standard SNAplus2 product
includes TN server, enabling TN3270 programs to access a host over the
SNA communications links provided by SNAplus2.
