It also has instructions on how to build the cable yourself.

Introduction

This HOWTO is for people who have Reliance or TATA Indicomm WLL phones andwish to access Internet on their desktops/laptops running GNU/Linux usingserial cable (NOT a USB CABLE).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).No software provided by Reliance was used, but I did search the Internet forthe modem query strings which are required during PPP setup.No software provided by Reliance was used, but I did search the Internet for the modem query strings which are required during PPP setup.I have tried this setup on Slackware Linux 10.1 with a 2.4.29 kernel and I ampretty confident that this trick will work on other Linux distributions as well.

System Requirements

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 recompilethe kernel with PPP support.You will need a GNU/Linux system with a kernel having PPP support pre-compiled.

I used a CAT 5 cable which has four pairs of UTPcopper. CAT 5 cable is the same cable which is used for networking your systemto 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:I built my cable myself.

Activating Internet Services on your Handset

To get Internet services activated on your handset you may contact the customercare center of your service provider. In the case of the Reliance the service is pre-activated.To get Internet services activated on your handset you may contact the customer care center of your service provider. In the case of the Reliance the service is pre-activated.For establishing the connection on a Reliance, the user name is the phone number without the prefix 0 in the STD code. For instance, if your STD code is0124 and telephone number is 3456789 then your user name is 1243456789. Your passwordis the same as your user name. When using the TATA Indicomm user name and password areinternet (without quotes).For establishing the connection on a Reliance, the user name is the phone number without the prefix 0 in the STD code.

Checking for PPP Support

Although PPP support is provided in almost all Linux distributions but it is stillbetter to check whether it is present on your system. You can use checkconfig or, betterstill, look into the /usr/sbin directory and locate PPP binaries with the commandAlthough PPP support is provided in almost all Linux distributions but it is still better to check whether it is present on your system.

Configuring your Phone

Currently Reliance comes with one of two brands of handsets: LG and Samsung. TATAIndicom also provides two handsets: LG and AXESSTEL.Currently Reliance comes with one of two brands of handsets: LG and Samsung.

PPP Configuration
