The final CxObject is the debug CxObject.  When a debug CxObject receives
a CxMessage, it sends debugging information to the serial port using
KPrintF().

    debugCxObj  = CxObj  *CxDebug(LONG ID);

The debug CxObject will KPrintF() the following information about itself,
the CxMsg, and the corresponding InputEvent structure:

    DEBUG NODE: 7CB5AB0, ID: 2
     CxMsg: 7CA6EF2, type: 0, data 2007CA destination 6F1E07CB
    dump IE: 7CA6F1E
     Class 1
     Code 40
     Qualifier 8000
     EventAddress 40001802

There has to be a terminal connected to the Amiga's serial port to receive
this information.  See the KPrintF() Autodoc (debug.lib) for more details.
Note that the debug CxObject did not work before V37.
