Introduction

The program TTGEN creates the file used to initialize and start up the run-time ZCOM sub-system. TTGEN reads an ascii configuration file that contains the details of the network structure and generates a binary memory image file to be used by ZMON. The file structure is detailed under “Tables and Data Structures” in the Multi-protocol ACC Programmer’s Reference Guide. ZMON reads the memory image file and sets up pointers for the ZCOM drivers, indicating where the tables lie in memory. ZMON also initializes all the buffers.
