Specifically, PPP masks characters (in a given range) that a modem 
might interpret as control characters and masks them. It transmits the
masked character preceded by a character which signals to PPP that the 
following character is masked. The receiving PPP implementation then 
decodes the masked character. Because of this, PPP can actually be somewhat
slower than SLIP, but it is more dependable. Assumably, that dependability
should save you time in the long run.
