you're on Windows. You can read about connecting and diagnosing

from the same set.

no, I mean the data exchanged between the client and the server over
the TCP/IP connection to perform the various functions, i.e. the
connection of the client to the server, the execution of a SQL
statement etc. Of course I could reverse engineer the API, but written
documentation would be *much* better...
