It is good that one asks, then!  ;-)

No.

There's nothing in the UG about the contents of the log.  It changes
according to our whim.

It will show the attempts to contact the port, and any the contents of any
responses.  I was going to send you a patch that would parse the reponse
completely in the log file, but I don't have a convenient way to test it
atm and it turns out Microsoft didn't include a description of that packet
-- not that it's so complex -- in their published documentation of the TDS
protocol.  

HTH.
