+ * DECnet object for servicing SSL.  We accept the inbound and speak a
+ * simple protocol for multiplexing the 2 data streams (application and
+ * ssl data) over this logical link.
+ *
+ * Logical names:
+ *    SSL_CIPHER	Defines a list of cipher specifications the server
+ *			will support in order of preference.
+ *    SSL_SERVER_CERTIFICATE
+ *			Points to PEM (privacy enhanced mail) file that
+ *			contains the server certificate and private password.
+ *    SYS$NET		Logical created by netserver.exe as hook for completing
+ *			DECnet logical link.
+ *
+ * Each NSP message sent over the DECnet link has the following structure:
+ *    struct rpc_msg { 
+ *      char channel;
+ *      char function;
+ *      short length;
+ *      char data[MAX_DATA];
+ *    } msg;
+ *
+ * The channel field designates the virtual data stream this message applies
+ * to and is one of:
+ *   A - Application data (payload).
+ *   R - Remote client connection that initiated the SSL connection.  Encrypted
+ *       data is sent over this connection.
+ *   G - General data, reserved for future use.
+ *
+ * The data streams are half-duplex read/write and have following functions:
+ *   G - Get, requests that up to msg.length bytes of data be returned.  The
+ *       data is returned in the next 'C' function response that matches the
+ *       requesting channel.
+ *   P - Put, requests that the first msg.length bytes of msg.data be appended
+ *       to the designated stream.
+ *   C - Confirms a get or put.  Every get and put will get a confirm response,
+ *       you cannot initiate another function on a channel until the previous
+ *       operation has been confirmed.
+ *
+ *  The 2 channels may interleave their operations, for example:
+ *        Server msg           Client msg
+ *         A, Get, 4092          ---->
+ *                               <----  R, get, 4092
+ *         R, Confirm, {hello}   ---->
+ *                               <----  R, put, {srv hello}
+ *         R, Confirm, 0         ---->
+ *                               .		(SSL handshake completed)
+ *                               .              (read first app data).
+ *                               <----  A, confirm, {http data}
+ *         A, Put, {http data}   ---->
+ *                               <----  A, confirm, 0
+ *
+ *  The length field is not permitted to be larger that 4092 bytes.
