About This Guide

Purpose

This guide provides the following:

Configuration and administration procedures

Configuration examples

Audience

This manual is intended for the person responsible for configuring and administering Digi One/PortServer TS 2/4. It assumes that this person has experience configuring network devices and is familiar with networking concepts.

Scope

This manual provides step-by-step instructions for configuring and administering Digi One/PortServer TS 2/4’s main features. It does not address how to configure every option, provide complete information on commands, or discuss hardware installation. These topics are covered in other documents in the Digi One/PortServer TS 2/4 library.

About Command Line Examples

In this manual, many command examples are broken up and placed on two lines of the manual. This is done to control where the line breaks, making it as easy to read as possible. When this is done, the second line of the command will be indented slightly, as shown below.

set menu range=6 t1="Console Management Menu" name="Console Management Menu" m3="Connect to System 1" c3="connect 1" m4="Connect to System 2" c4="connect 2"

About Entering Commands on the Command Line

On the Digi One/PortServer TS 2/4 command line, do not force a line break (by pressing Enter or Return). This will commit the command before you finish adding all command fields. If your terminal does not support wrapping to the next line and long commands scroll out of sight, the easiest way to enter long commands is by breaking the command into multiple commands as shown below. If you use this method, however, you must let the Digi One/PortServer TS 2/4 know that you are configuring the same entity, such as the same port, menu, or line. This is done by repeating the range or name field in each command.

set menu t1="Console Management Menu" range=6

set menu range=6 name="Console Management Menu" m3="Connect to System 1" set menu range=6 c3="connect 1" m4="Connect to System 2"

set menu range=6 c4="connect 2"
