  %  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
  %  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.
