SNA IMF Programmer's Reference Manual

Overview of SNA IMF 

Systems Network Architecture Interactive Mainframe Facility (SNA IMF)is a
Hewlett-Packard software product based on IBM's Systems Network
Architecture (SNA). SNA IMF allows an HP 3000 to communicate with a
remote host in an IBM 3270 environment.  Using SNA IMF, the HP 3000
functions as a Type 2.0 nodein an SNA network.  Devices attached to the
HP 3000 emulate the functions of IBM 3278 display stations and IBM 3287
printers. 

The HP 3000 plays the same role in an SNA network that the IBM 3276 or
3274 Cluster Controllerplays in a remote IBM environment.  Figure 1-1
shows how the HP 3000 fits into the IBM 3270 environment.

SNA IMF supports the "base set" of IBM 3274 Cluster Controller functions.
The following 3274 functions are not supported:

      Extended color 
      Structured fields and attribute processing 
      APL/Text 
      REQMS and RECFMS 
      Operator-entry assist 
      NetView support including the Alert function 
      Magnetic-stripe readers and bar-code readers 
      Operator type-ahead feature 
      Dual session support 

SNA IMF allows HP 3000 programs and attached devices to exchange data
with application subsystems on an IBM host.  These IBM application
subsystemsinclude the Customer Information Control System 
(CICS),Information Management System (IMS), and Time Sharing Option 
(TSO).
