  13           You'll have to say Y if your computer contains a network card that
  14           you want to use under Linux. If you are going to run SLIP or PPP over
  15           telephone line or null modem cable you need say Y here. Connecting
  16           two machines with parallel ports using PLIP needs this, as well as
  17           AX.25/KISS for sending Internet traffic over amateur radio links.

  65           If you use SLIP or PPP, you might want to say Y here. Since this
  66           thing often comes in handy, the default is Y. It won't enlarge your

  79           SLIP (the protocol for sending Internet traffic over telephone
  80           lines) or PPP (a better SLIP) on them, you can make them behave like
  81           one double speed connection using this driver.  Naturally, this has
  82           to be supported at the other end as well, either with a similar EQL
  83           Linux driver or with a Livingston Portmaster 2e.
