 * OVERVIEW:  Prototypes for supporting using datagrams on the
 *            Generic Connection framework.  If a target platform
 *            wants to support these networking
 *            capabilities, a platform-specific implementation of the 
 *            functions below must be provided in the Vm<Port>/src directory,
 *            where <Port> is the name of your target platform
 *            (e.g., Win, Unix, Pilot).  A default implementation is
 *            provided in VmExtra/src.
