Understanding TN3270
What Is TN3270?
Chapter 1 19
Audit log file
A single file that contains a record of all significant
system events. The name of this file, and the level of
detail recorded in it, are specified in the configuration
file.
Trace files
One or more optional trace files record the data
transferred between the TN3270 program and the host,
or between a HLLAPI application and the TN3270
program. You can use these files to help you debug
specific problems. Tracing is normally disabled because
it degrades system performance.
All these files are simple text files; you can view them
with any ASCII text editor, such as vi.
TN3270 Features Supported
The TN3270 product supports both the standard TN3270 features and
the extended TN3270E features that are described in the Internet 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 TN3270E features are supported only if the directly connected host,
or the communications product that provides the TN Server function,
also supports the TN3270E features. When the connection is established,
the host or communications product negotiates with the TN3270 product
to determine the level of support.
You can configure the level of support that you desire for the TN3270
product by specifying a value for the tn3270_support field in the host
record. You can determine the level of support that was negotiated by
looking at the Control Display Sessions dialog box or the Control Printer
