depend on the implementation of the BCA component. </p> <p>The first parameter
of the method is the option level. It separates the options in logical categories,
such as general settings (common to all BCA components), serial settings,
or implementation-specific settings. You should define an enumeration for
your option levels. </p> <p>The second parameter is a constant representing
the control option. Typical control options reset the transmission or reception
buffer or start the monitoring of the EIA-232 control line. </p> <p>The third
parameter points to the value of the specified option. For some control options,
the BCA component modifies this value to return information to the caller. </p> </section>
