*     XPROTD.c                                       
*
* DESCRIPTION
*
*      Demonstration of the Extended Protocol Package consisting of;
*      Telnet, TFTP Server, FTP Server, FTP Client.  The demo requires
*      two parameters; (1) local ip address to be used with each of the
*      three servers and (2) remote ip address to which the ftp client
*      will connect.  These two parameters are configured in the demoi.c
*      file.
*
*      The four applications will use DEMOI_Local_Ip as their local ip
*      address.  The FTP client will connect to DEMOI_FTP_Server.
*
*      Within this file, configurable parameters are located in the
*      section titled "USER CONFIGURABLE PARAMETERS."
