Unsure.. I need to look into this since I'm not really familiar with
Discard socket. I have tried both uncommenting the and setting
it to the machine I'm trying to use telnet on. (ie my
linux box)

I have not changed anything on the demo except to enable BootP and add
more files handles. When I use the sniffer It does not look to me that
the Rtems box tries to except the telnet session. But I need to look
into this more but I really thought the netDemo should work pretty much
as is.
