OVERVIEW OF THE SOFTWARE INSTALLATION
You must do the following to install the SerialNET software:
1. Make sure you have successfully installed the AlphaNET software, as described in Chapter 3 of
this book.
2. After copying the software onto the computer, run the NETINI program and enter the Product
Installation Code (PIC).
3. Create a unique network initialization file, SERnnn.NIN, to install your computer onto the
network with a unique group and node designation. The network initialization file is also
described in Chapter 3.
4. Modify your System Initialization Command file to define the serial interface connection you
wish to use, and to execute the necessary programs to bring up the SerialNET system.
