|  | 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. | 
|  | 34 |  | 
|  | 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. | 
|  | 58 |  | 
|  | 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. |
