Installing SerialNET Page 4-3

AlphaNET Installation Guide, Revision 05

DO NOT modify your system initialization command file directly, but create a test copy,

TEST.INI, and modify that. Once this copy is executing properly, you may replace your original

system initialization command file with the test copy.

CREATING A NETWORK INITIALIZATION FILE FOR SERIALNET

The following is an example of the file (SERnnn.NIN) that will install your computer on the network.

For more details on the network initialization file, see Chapter 3.

The sample below shows a typical network initialization file for SerialNET. Note you must specify the

SERIAL driver, and must turn NODECHECK off.

DRIVER = SERIAL ; Network driver

NETWORK = 3 ; Network number

GROUP = 1 ; Group number

NODE = 1 ; Node number (unique

; within a group and network)

NODECHECK = OFF ; Checks node # before request

NAME = Serial Network ; Descriptive name

DEFINING THE SERIALNET TERMINAL CONNECTION

SerialNET uses a standard terminal port as its physical connection. This terminal port must be defined to

AMOS through the use of the TRMDEF statement in the system initialization command file, the same as

for any other terminal.

The only unique thing about defining a terminal as a SerialNET connection is the naming of the terminal.

So the SerialNET software can locate the connection you wish to use, it requires the terminal be named

using the form SERnnn, where nnn is the network number associated with the terminal connection.

Thus, to define a terminal port for use with network 3, you would define a terminal named SER003,

using a command similar to the following:

TRMDEF SER003,AM355=16:38400,TELTYP,100,100,100,,NULL

Note SerialNET requires the NULL modem driver be specified at the end of the TRMDEF command. It

also requires that no line editor be installed on the port. The terminal driver is ignored by SerialNET, but

should be specified as TELTYP to reduce overhead.

SETTING UP ERSATZ NAMES

You will probably want to set up ersatz device names for the nodes on your SerialNET, as described in

Chapter 3. By using ersatz device names, you can avoid the use of lengthy and cumbersome network

address numbers.
