PPP's escape character is '~', and any occurences of this character must be escaped. So, to double the effectiveness of a ping flood, pings can be filled with a tilde. DoS
Note that this only applies to asynchronous HDLC like encapsulation for PPP. With true HDLC, this attack will still do damage, but only to the tune of a 12.5% degradation. So it rarely has any effect except on the network edge where you might find a modem. -Phil
