   9          Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
  10          connect to your Internet service provider or to connect to some
  11          other local Unix box or if you want to configure your Linux box as a
  12          Slip/CSlip server for other people to dial in. SLIP (Serial Line
  13          Internet Protocol) is a protocol used to send Internet traffic over
  14          serial connections such as telephone lines or null modem cables;
  15          nowadays, the protocol PPP is more commonly used for this same
  16          purpose.
  17
  18          Normally, your access provider has to support SLIP in order for you
  19          to be able to use it, but there is now a SLIP emulator called SLiRP
  20          around (available from
  21          <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  22          allows you to use SLIP over a regular dial up shell connection. If
  23          you plan to use SLiRP, make sure to say Y to CSLIP, below. The
  24          NET-3-HOWTO, available from
  25          <http://www.tldp.org/docs.html#howto>, explains how to
  26          configure SLIP. Note that you don't need this option if you just
  27          want to run term (term is a program which gives you almost full
  28          Internet connectivity if you have a regular dial up shell account on
  29          some Internet connected Unix computer. Read
  30          <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
  31          support will enlarge your kernel by about 4 KB. If unsure, say N.
  32
  33          To compile this driver as a module, choose M here. The module
  34          will be called slip.

  36config SLHC
  37        tristate
  38        ---help---
  39          This option enables Van Jacobsen serial line header compression
  40          routines.

  44config SLIP_COMPRESSED
  45        bool "CSLIP compressed headers"
  46        depends on SLIP
  47        select SLHC
  48        ---help---
  49          This protocol is faster than SLIP because it uses compression on the
  50          TCP/IP headers (not on the data itself), but it has to be supported
  51          on both ends. Ask your access provider if you are not sure and
  52          answer Y, just in case. You will still be able to use plain SLIP. If
  53          you plan to use SLiRP, the SLIP emulator (available from
  54          <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  55          allows you to use SLIP over a regular dial up shell connection, you
  56          definitely want to say Y here. The NET-3-HOWTO, available from
  57          <http://www.tldp.org/docs.html#howto>, explains how to configure
  58          CSLIP. This won't enlarge your kernel.

  60config SLIP_SMART
  61        bool "Keepalive and linefill"
  62        depends on SLIP
  63        ---help---
  64          Adds additional capabilities to the SLIP driver to support the
  65          RELCOM line fill and keepalive monitoring. Ideal on poor quality
  66          analogue lines.
  67
  68config SLIP_MODE_SLIP6
  69        bool "Six bit SLIP encapsulation"
  70        depends on SLIP
  71        ---help---
  72          Just occasionally you may need to run IP over hostile serial
  73          networks that don't pass all control characters or are only seven
  74          bit. Saying Y here adds an extra mode you can use with SLIP:
  75          "slip6". In this mode, SLIP will only send normal ASCII symbols over
  76          the serial device. Naturally, this has to be supported at the other
  77          end of the link as well. It's good enough, for example, to run IP
  78          over the async ports of a Camtec JNT Pad. If unsure, say N.
