Users on Windows can use the ODBC Data Source Administrator to set these parameters; see Section 5.3, “Configuring a Connector/ODBC DSN on Windows” on how to do that, and see Table 5.1, “Connector/ODBC DSN Configuration Options” for information on the options and the fields and check boxes they corrrespond to on the graphical user interface of the ODBC Data Source Administrator.
