/*
 * Plugins may access comm ports for direct output.
 * The general program flow for a plugin may look something like this
 * pseudo-code:
 * 1.  Plugin will query OCPN core for a list of active comm drivers.
 * 2.  Plugin will inspect the list, and query OCPN core for driver
 *     attributes.
 * 3.  Plugin will select a comm driver with appropriate attributes for output.
 * 4.  Plugin will register a list of PGNs expected to be transmitted
 *     (N2K specific)
 * 5.  Plugin may then send a payload buffer to a specific comm driver for
 *     output as soon as possible.
 *
 * The mechanism for specifying a particular comm driver uses the notion of
 * "handles". Each active comm driver has an associated opaque handle, managed
 * by OCPN core. All references by a plugin to a driver are by means of its
 * handle. Handles should be considered to be "opaque", meaning that the exact
 * contents of the handle are of no specific value to the plugin, and only
 * have meaning to the OCPN core management of drivers.
