Make your own Command for wll

February 13, 2009

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=0x0001

save and exit

After that change the permission

chmod +x wll to make it executable

Know you have your own command wll

apt-add cdrom then enter the 2nd disk likewise….

2)You have to register the device to the kernel

* modprobe usbserial vendor=0x15eb product=0x0001

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:

Hack Your Parallel Port

September 9, 2008

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,0x378); /* it will make the pin 2-9 high(0xff eight 1’s) & 0x378 is the port address*/
9. sleep(1);
10. outb(0x00,0x378);/*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
