ZCOM Message Handling
Overview
Chapter 224
Overview
ZCOM message handling is achieved through logical constructs called
ZLUs which maintain queues for messages to terminals and programs.
The terminal ZLUs are either defined at ZCOM configuration time using
ttgen, or can be created programmatically using the Dynamic System
Configuration functions; the program ZLUs are allocated dynamically
from a pool of ZLUs when requested.
