Section 4. Global Events Queue Multiple Devices Shown

 

 

Another section of the same Global Event Queue shows that multiple devices reported events to this queue. Below we see that those events include: VDisplay, Keyboard, Andisplay, and Tone events.

 

 

Andisplay Events

 

Similar to the VDisplay events described in the last section, Andisplay events contain a millisecond time, time-of-day, sequence number, a starting offset, a length and a display string.

 

 

Tone Events

 

Tone events include frequency and duration.

 

 

Keyboard Events

 

Keyboard events contain a scancode, function code and a text label. Scancode are hardware defined.

 

 

Connecting to MIB for Keyboard Function Code and Text Label

 

When the InSight Dump Formatter first encounters a Keyboard event it attempts to connect to the MIB to resolve the scancode and get the corresponding function code and key text label. For more information see Using the InSight Dump Formatter.

 

 

Dump Output Sample

 

In the example shown below the highlighted section shows that the InSight Dump Formatter was able to connect to the MIB and retrieve the corresponding function code of 76 and key label text of “Signon” for the scan code x20. If the connection to the MIB had failed, the KeyBd events are still formatted, however the fCode will be ‘0’ and text will be blank.
