It serves + the same purpose: sending Internet traffic over telephone (and other + serial) lines. Ask your access provider if they support it, because + otherwise you can't use it; most Internet access providers these + days support PPP rather than SLIP. + + To use PPP, you need an additional program called pppd as described + in the PPP-HOWTO, available at + . Make sure that you have + the version of pppd recommended in . + The PPP option enlarges your kernel by about 16 KB. + + There are actually two versions of PPP: the traditional PPP for + asynchronous lines, such as regular analog phone lines, and + synchronous PPP which can be used over digital ISDN lines for + example. If you want to use PPP over phone lines or other + asynchronous serial lines, you need to say Y (or M) here and also to + the next option, "PPP support for async serial ports". For PPP over + synchronous lines, you should say Y (or M) here and to "Support + synchronous PPP", below. + + If you said Y to "Version information on all symbols" above, then + you cannot compile the PPP driver into the kernel; you can then only + compile it as a module.

Even if they don't support it, + it is safe to say Y here. + + The PPP Deflate compression method ("PPP Deflate compression", + above) is preferable to BSD-Compress, because it compresses better + and is patent-free. + + Note that the BSD compression code will always be compiled as a + module; it is called bsd_comp and will show up in the directory + modules once you have said "make modules".
