   %  SLIP (Serial Line IP)
  -% 
  +%
   %  The idea behind SLIP is very simple. IP-packets are sent over
   %  a serial line. Each packet is terminated with END (digtal 192).
   %  If END occurs in the packet the sequence ESC (digital 219) and
  -%  ESCEND (digital 220) is sent instead. If ESC occurs then the 
  +%  ESCEND (digital 220) is sent instead. If ESC occurs then the
   %  sequence ESC ESCESC (digital 221) is sent instead.
  -% 
  +%
   %  An optimisation is to start all packets with an END token. This
   %  has the effect of flushing all line noise that may have occured.
   %
  -%  Both the sender and the reciever need to know each others 
  -%  IP-addresses.
