 * OVERVIEW:  Prototypes for supporting serial communication ports.
 *            If a target platform wants to support serial ports,
 *            a platform-specific implementation of the functions
 *            must be provided in the Vm<Port>/src directory,
 *            where <Port> is the name of your target platform
 *            (e.g., Win, Unix, Pilot).
