Friends…. while buying a new laptop, check these sites which will give you
which all linux distros will support which all laptops…..

Those who have read my Bsnl wll article, there is a problem in it. Every time you restart your Linux machine you have to modprobe. So what will we do????
Simple make a command but How???
Take a terminal and type
$PATH (Every thing should be in CAPITAL)
this is the output in my debian machine
bash:/usr/local/bin:/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin/X11:/usr/games: No such file or directory
When you type a command in a shell, shell searches for executable file in directory mentioned by the above command..
So go to /usr/local/bin
make a file wll vi wll
add to lines
modprobe usbserial vendor=0x15eb product=0×0001
wvdial
save and exit
After that change the permission
chmod +x wll to make it executable
Know you have your own command wll

1) You Have To Install Wvdail
* apt-get install wvdial
If you Don’t have the package download. If you are using Debian you add the packages of Disc 2&3
apt-add cdrom then enter the 2nd disk likewise….
2)You have to register the device to the kernel
* modprobe usbserial vendor=0x15eb product=0×0001
ID can be seen by using the command lsusb -v
3) Also add The module
* modprobe ppp_generic
4)See & configure your modem
* wvdialconf ( MODEM-usually – /dev/ttyACM0… OR /dev/USB0… )
4)edit the file in /etc/wvdial.conf with U’r favourite editor
* vi /etc/wvdial.conf
5)make it like this
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = at+crm=1;+cmux=1;+cps=33;+cta=0
Modem Type = Analog Modem
Stupid Mode = yes
Baud = 460800
New PPPD = yes
Modem = /dev/ttyUSB0
Phone = #777
ISDN = 0
Username = Your Phone No: Without 0;
Password = Password is your last 4 digit of your ph: no:
6)Dail
* wvdial
7)take another terminal and ping to see connection to Internet
* ping http://www.google.com (you will raceive data)
8)Take a browser epiphany or mozilla its play time
* epiphany http://www.google.com

Parallel Port Description
For blinking LED you have to write a code. i.e. first you have to make the data pin high(pin no:2-9)
we will be writing a C code:
1. #include”stdio.h”
2. #include”sys/io.h” /*Header file for iopl(),outb()*/
3. main()
4. {
5. iopl(3);/*to give your program access to all I/O ports*/
6. while(1)
7. {
8. outb(0xff,0×378); /* it will make the pin 2-9 high(0xff eight 1′s) & 0×378 is the port address*/
9. sleep(1);
10. outb(0×00,0×378);/*it will make the pin 2-9 low */
11. sleep(1);
12. }
13. }
Now comes your circuit. Here we have connected only 1 LED to pin2 and pin 19 is the ground.
You can connect LED to pin 2-9 with a resistor(1k) & control these pins in different way
