Parameter Types and Groups

This section describes parameter types and functional groups.

Read/write, Read-only, and Write-only Parameters

Parameters are read/write, read-only, or write-only. The parameters you set when configuring the terminal are read/write parameters. Read-only parameters report various types of statistical information.

Parameters containing passwords and encryption keys are write-only. When displayed through a TELNET connection, write-only parameter values are shown as follows:

When displayed through Change Setup Parameters, write-only parameter values are shown as follows:

Parameter Groups

The parameter groups are listed in Table 6-1. The name of each parameter within a group begins with the group name. Groups correspond, for the most part, to the hide boxes displayed in Change Setup Parameters when invoked from the Console, except for the pref group, which appears only in Change User Preferences.
