      init-word:&lt;current-OTP&gt;:&lt;new-params&gt;:&lt;new-OTP&gt;

   In augmented BNF syntax and with the definitions already provided,
   the syntax of the "init-hex" response is:

   init-hex-response = "init-hex:" current-OTP ":" new-params ":"
                        new-OTP NL

   current-OTP     = hex-64bit
   new-OTP         = hex-64bit

   new-params      = algorithm SPACE sequence-number SPACE seed
   algorithm       = "md4" / "md5" /
