1# 2# SLIP network device configuration 3# 4 5config SLIP 6 tristate "SLIP (serial line) support" 7 depends on TTY 8 ---help--- 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. 35 36config SLHC 37 tristate 38 ---help--- 39 This option enables Van Jacobsen serial line header compression 40 routines. 41 42if SLIP 43 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. 59 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.
