The SHOW command shows the relay settings. When showing settings, the

settings; see SET for information on settings organization. The relay displays
each setting in the order specified in the settings tables in the Section 10:
Settings. When you are using a terminal and you specify a setting in the
middle of a settings category, the relay displays the category title, then
proceeds with the class or instance settings from the setting that you specified.
See Making Simple Settings Changes on page U.4.13 for more information on
entering and viewing relay settings.
