PPP for ELKS
------------
'ppp' just starts the LCP negotiation - exchanges the configure requests
and acks. None of the othe options are negotiated. It needs the NCP to carry on the next phase of negotiation.

To Run
------
Connect the machine running ELKS with a machine running Linux via a null-modem cable. Start the ppp daemon on the linux machine with no negotiation options - 

--> Assuming that the serial cable is connected on ttyS0 on both machines.

--> pppd -detach debug default-asyncmap nopcomp noaccomp nomagic nocrtscts noip noccp silent 9600 /dev/ttyS1 &

Start ppp on ELKS
--> ppp /dev/ttyS0
