Hi Alvaro,

One more question:

Are you suggesting that the dummy packet is dependent of the active query?

It seems good to me what you have done.

Take Firebird 1.5, and take FbConfManager. Firebird 1.5 as much paramters in
the config file, but they are well explained in FbConfManager.

Good question. I always think that this was just a small dummy packet,
always the same size.

Did you try without any query at all? Just connect to the server, and don't
even attach to a database? This will give you a more precise answer. One
thing that could happen is that what you are seeing is some "fetch record"
from the database, not the dummy packet.
