+config SLIP
+       tristate "SLIP (serial line) support"
+       depends on TTY
+       ---help---
+         Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
+         connect to your Internet service provider or to connect to some
+         other local Unix box or if you want to configure your Linux box as a
+         Slip/CSlip server for other people to dial in. SLIP (Serial Line
+         Internet Protocol) is a protocol used to send Internet traffic over
+         serial connections such as telephone lines or null modem cables;
+         nowadays, the protocol PPP is more commonly used for this same
+         purpose.
+
+         Normally, your access provider has to support SLIP in order for you
+         to be able to use it, but there is now a SLIP emulator called SLiRP
+         around (available from
+         <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+         allows you to use SLIP over a regular dial up shell connection. If
+         you plan to use SLiRP, make sure to say Y to CSLIP, below. The
+         NET-3-HOWTO, available from
+         <http://www.tldp.org/docs.html#howto>, explains how to
+         configure SLIP. Note that you don't need this option if you just
+         want to run term (term is a program which gives you almost full
+         Internet connectivity if you have a regular dial up shell account on
+         some Internet connected Unix computer. Read
+         <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
+         support will enlarge your kernel by about 4 KB. If unsure, say N.
+
+         To compile this driver as a module, choose M here. The module
+         will be called slip.
+
+config SLHC
+       tristate
+       ---help---
+         This option enables Van Jacobsen serial line header compression
+         routines.
+
+if SLIP
+
+config SLIP_COMPRESSED
+       bool "CSLIP compressed headers"
+       depends on SLIP
+       select SLHC
+       ---help---
+         This protocol is faster than SLIP because it uses compression on the
+         TCP/IP headers (not on the data itself), but it has to be supported
+         on both ends. Ask your access provider if you are not sure and
+         answer Y, just in case. You will still be able to use plain SLIP. If
+         you plan to use SLiRP, the SLIP emulator (available from
+         <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
+         allows you to use SLIP over a regular dial up shell connection, you
+         definitely want to say Y here. The NET-3-HOWTO, available from
+         <http://www.tldp.org/docs.html#howto>, explains how to configure
+         CSLIP. This won't enlarge your kernel.
+
+config SLIP_SMART
+       bool "Keepalive and linefill"
+       depends on SLIP
+       ---help---
+         Adds additional capabilities to the SLIP driver to support the
+         RELCOM line fill and keepalive monitoring. Ideal on poor quality
+         analogue lines.
+
+config SLIP_MODE_SLIP6
+       bool "Six bit SLIP encapsulation"
+       depends on SLIP
+       ---help---
+         Just occasionally you may need to run IP over hostile serial
+         networks that don't pass all control characters or are only seven
+         bit. Saying Y here adds an extra mode you can use with SLIP:
+         "slip6". In this mode, SLIP will only send normal ASCII symbols over
+         the serial device. Naturally, this has to be supported at the other
+         end of the link as well. It's good enough, for example, to run IP
+         over the async ports of a Camtec JNT Pad. If unsure, say N.
