Received ALE messages are available for review under the ALE_RX
selection (Figure 3-59). They are shown in order from the newest to
the oldest message. The messages can be reviewed by turning the
VAR knob with the cursor on the index or the message field.
The SoundFrom selection will display the ALE addresses heard since
