To turn the option on, type:

Displaying packets

You can view wdDialout output in the diagnostic monitor. This section shows

several examples.

Example 1

In the following example, the Pipeline unit’s time and date have not been

explicitly set, so the date and time in the captured packet is invalid. The phone

number dialed on receipt of this packet is 92233002.
