>You will need a GNU/Linux system with a kernel having PPP support pre-compiled.
I have tested that both the 2.4.29 kernel and the 2.6.x series kernel work fine. Performance seems to be better using a 2.6.x kernel.
If you see that some kernel modules are missing then configure and recompile
the kernel with PPP support.</P

>Check with <A

> for the configuration of
PPP.</P

>A connecting serial cable which has on one end an RJ-45 connector which plugs into
the phone and on the other end has an RS-232 serial connector which is plugged into the serial port of the PC.</P
><P
>I built my cable myself. I used a CAT 5 cable which has four pairs of UTP
copper. CAT 5 cable is the same cable which is used for networking your system
to a LAN. While you can use any type of cable, CAT 5 will assure a good quality of the signal that is sent over the wire. A typical configuration looks like this:</P
