If the Display Mode is selected with a "D", current status and configuration data may be examined but cannot be
modified. This mode is useful for verifying ATT configuration. This mode cannot be used to actively monitor ATT
operation, as normal ATT operation is suspended when the Model 1200 is connected.

If the Alter Mode is selected with an "A", all applicable configuration parameters can be modified. Figure 3-2 on
page 12 illustrates the display mode menu tree and Figure 3-1 on page 12 illustrates the Alter Mode menu tree. The

scroll through related items.
