Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

dongel is airtel 3g stick from which i can access internet
i need to use port no in my project ....plz help me to find port no
private static String port = " "; //Modem Port.
private static int bitRate = 115200; //this is also optional. leave as it is.
private static String modemName = "ZTE"; //this is optional.
private static String modemPin = "0000"; //Pin code if any have assigned to the modem.
private static String SMSC = ""; //Message Center Number ex. Mobitel
Note that udev maps devices all over the place, especially serial ports,... so you can have your modem plugged into the first USB port, and this time it'll be /dev/ttyUSB0,... but next time it could be /dev/ttyUSB1 ... No rhyme or reason... The Roman Catholic Church has the mysteries of faith,... Linux users have udev. Udev rules help tidy it up.
To determine the details of the ACTUAL physical device you'd be looking at the /proc system... Which is part of what lsusb does... In the above case, bus 1, assigned as device 5.
