Strange, but they are in erlang, not strings:


since a string is a list, they work quite well. :)

   * [...] Note that 120 sec is defined in the protocol as the maximum
   * possible RTT.  I guess we'll have to use something other than TCP
   * to talk to the University of Mars.
   * PAWS allows us longer timeouts and large windows, so once implemented
   * ftp to mars will work nicely.
