3104/3105 Control Program
Generating and Loading the 3704/3705 Control Program Several commands and EXEC procedures generate and load the 3104/3105 control program. These commands and EXEC procedures are executed in a eMS virtual machine. The commands are a part of the VM/310 system and
are distributed with it. A special version of the IBM 3104/3105 Network Support Package for OS/VS, Order No. 5144-ANl EP/VS from PID for use under VM/310. This version of the
contains two CMS EXEC procedures for generating 3704/3705 control programs.

This section describes the step by step procedure for generating and
loading the 3704/3105 control program. Each EXEC procedure and command
is described as it is used. The action required at each step is
summarized first and then explained in detail. The preceding "Planning
Considerations" section, lists all the documentation, physical devices,
programming, and other materials you need before starting to generate
the 3 7 04/3705 control program. Step 1. Log On the VM/370 System VM/370 supports the EP type of control program. The VM/370 system that
you load also must have been generated with: • The IBM 3104 or 3105 Communications Controllers specified on a RDEVICE system generation macro. • The NAMENCP macro coded to create an entry in the VM/310 system name
table (DMKSNT) for the 3104/3105 control program. • Space reserved on a CP-owned volume to contain a copy of the 3704/3105 control program.
These VM/310 system generation requirements are described in Part 1. Step 2. Set Up a eMS Virtual Machine You must IPL a CMS virtual machine and be sure that the necessary
devices are attached.
The 3104/3105 control program is generated using commands and EXEC procedures that execute in a CMS virtual machine. The C8S virtual
machine must have the following resources: • At least 1024K of virtual storage. • One tape drive (9 track, 800 or 1600 bpi). • Space available on the C8S A-disk (120 cylinders of a 3330 disk, all 203 cylinders of a 2314 disk, 300 cylinders of a 3340 disk, or 60 cylinders of a 3350 disk.
