>1. Introduction</H1
><P
>This HOWTO is for people who have Reliance or TATA Indicomm WLL phones and
wish to access Internet on their desktops/laptops running GNU/Linux using
serial cable (NOT a USB CABLE).</P
><P
>No software provided by Reliance was used, but I did search the Internet for
the modem query strings which are required during PPP setup.</P
><P
>I have tried this setup on Slackware Linux 10.1 with a 2.4.29 kernel and I am
pretty confident that this trick will work on other Linux distributions as well. </P
><P
>The HOWTO assumes that you have a fair knowledge about your Linux distribution (BSD or System V style) and that PPP support is pre-compiled in your Linux kernel.</P
><P
>In this HOWTO we are talking about the serial cable for the following reasons:</P
><P
></P
><OL
TYPE="1"
><LI
><P
>The cable provided by Reliance or TATA is very expensive (about 1400 rupees)
and the software provided supports only MS Windows.The cable
typically has a USB interface on one end and an RJ-45 interface on the
other. However, for these phones phones a cheaper cable is available
on the market (only 100 rupees). This cable has a serial interface on one
end and an RJ-45 on the other. You can make this cable yourself.
The procedure is discussed later in this HOWTO. Why waste money when
you can assemble your own cable or purchase the cheaper one?</P
></LI
><LI
><P
>USB cables have some glitches for the WLL handsets, especially
the LG ones. I have no idea about other handsets, your input is welcome if you know about other sets. The
advantage in using a USB cable is that you can connect at 153.6 kbps as the handsets have an inbuilt
modem which is capable for speeds upto 170kbps.
</P
></LI
><LI
><P
>On the numerous forums I searched on the net I found that all talked
only about the USB cable and not about the serial one. I thought it was high
time to write this HOWTO to help fellow Linux users. </P

>2. System Requirements</H1
><P
>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
><P
>Check with <A
HREF="#sect_04"
>Section 4</A
> for the configuration of
PPP.</P
><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

not require a driver or anything. After you have connected your phone
to the cable, the cable is plugged in either COM1 or COM2 (and not COM3 or
COM4, as these are virtual ports).</P
