  5. tristate "SLIP (serial line) support"
  6. ---help---
  7. Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
  8. connect to your Internet service provider or to connect to some
  9. other local Unix box or if you want to configure your Linux box as a
  10. Slip/CSlip server for other people to dial in. SLIP (Serial Line
  11. Internet Protocol) is a protocol used to send Internet traffic over
  12. serial connections such as telephone lines or null modem cables;
  13. nowadays, the protocol PPP is more commonly used for this same
  14. purpose.
  15. Normally, your access provider has to support SLIP in order for you
  16. to be able to use it, but there is now a SLIP emulator called SLiRP
  17. around (available from
  18. <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  19. allows you to use SLIP over a regular dial up shell connection. If
  20. you plan to use SLiRP, make sure to say Y to CSLIP, below. The
  21. NET-3-HOWTO, available from
  22. <http://www.tldp.org/docs.html#howto>, explains how to
  23. configure SLIP. Note that you don't need this option if you just
  24. want to run term (term is a program which gives you almost full
  25. Internet connectivity if you have a regular dial up shell account on
  26. some Internet connected Unix computer. Read
  27. <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
  28. support will enlarge your kernel by about 4 KB. If unsure, say N.
  29. To compile this driver as a module, choose M here. The module
  30. will be called slip.
  31. config SLHC
  32. tristate
  33. ---help---
  34. This option enables Van Jacobsen serial line header compression
  35. routines.
  36. if SLIP
  37. config SLIP_COMPRESSED
  38. bool "CSLIP compressed headers"
  39. depends on SLIP
  40. select SLHC
  41. ---help---
  42. This protocol is faster than SLIP because it uses compression on the
  43. TCP/IP headers (not on the data itself), but it has to be supported
  44. on both ends. Ask your access provider if you are not sure and
  45. answer Y, just in case. You will still be able to use plain SLIP. If
  46. you plan to use SLiRP, the SLIP emulator (available from
  47. <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  48. allows you to use SLIP over a regular dial up shell connection, you
  49. definitely want to say Y here. The NET-3-HOWTO, available from
  50. <http://www.tldp.org/docs.html#howto>, explains how to configure
  51. CSLIP. This won't enlarge your kernel.
  52. config SLIP_SMART
  53. bool "Keepalive and linefill"
  54. depends on SLIP
  55. ---help---
  56. Adds additional capabilities to the SLIP driver to support the
  57. RELCOM line fill and keepalive monitoring. Ideal on poor quality
  58. analogue lines.
  59. config SLIP_MODE_SLIP6
  60. bool "Six bit SLIP encapsulation"
  61. depends on SLIP
  62. ---help---
  63. Just occasionally you may need to run IP over hostile serial
  64. networks that don't pass all control characters or are only seven
  65. bit. Saying Y here adds an extra mode you can use with SLIP:
  66. "slip6". In this mode, SLIP will only send normal ASCII symbols over
  67. the serial device. Naturally, this has to be supported at the other
  68. end of the link as well. It's good enough, for example, to run IP
  69. over the async ports of a Camtec JNT Pad. If unsure, say N.
