  I know of no such option, but you could certainly add on.
  Knowing you, I'd go the "slattach" way. The kernel then does the data
encap/decap for you.

  Go read the spec. PPP, particularly sync-PPP, is VERY simple.

  The 1/2-byte protocol number encoding is a little bizarre at first, but
there are some good noise-resistance reasons there. This is Bill Simpson at
