Distributed dialogs via LU6.1

The LU6.1 protocol (Logical Unit 6.1) is a SNA protocol defined by IBM. It has been continuously developed and has become the industry standard. Communication is performed with transaction management over multiple applications.

In addition to using LU6.1 to connect UTM applications, you can also connect UTM applications with CICS and IMS applications running on IBM computers.

The sections below explain the programming aids provided by openUTM for distributed processing, the rules for these dialogs and how you can use existing program units as an LU6.1- job submitter.
