When the client detected that server disconnected it due to the timeout,
first of all it(client) closes connection to the server, and then sets error
code 1023: Connection timed out.
So to reconnect in such case you can simply open it again with the
same set of parameters, i.e.
    OpenDataBase(<the same database name>);
But keep in mind, that all your stored references to all database objects
(such like cursors, fields, tables) became invalid by that time, when you
got 1023 error.

You DO NOT need to call any of these routines since at this moment
connection already closed.

What is error 9? It does not seems like a socket error code...
Is this a MAC-specific error code?
