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

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

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

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