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 node in 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 Controller plays in a remote IBM
environment. Figure 1-1 “The HP 3000 in the IBM 3270 Environment” 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:
Structured fields and attribute processing
NetView support including the Alert function
Magnetic-stripe readers and barcode readers
Operator type-ahead feature
SNA IMF allows HP 3000 programs and attached devices
to exchange data with application subsystems on an IBM host. These
IBM application subsystems include the Customer Information
Control System (CICS), Information Management
System (IMS), and Time Sharing Option (TSO).
