How to enable TATA Photon whiz on Ubuntu 9.04/Fedora 11

For all those who are using TATA Photon whiz (Hauwei -EC121 or others) these is small - "How to for Ubuntu 9.04 Jaunty Jackalope & Fedora 11" ,which by default can't Plug n play (atleast for me on Ubuntu :))even with Network Manager Applet -->Mobile broadband --> Country = India --> Provider -->Tata indicom ( Plug2Surf) -->Uname: internet,Password=internet,Ph =#777 ( As its CDMA).

# Ubuntu 9.04 Photon Whiz set up

1)By default Ubuntu 9.04 doesn't have wvdial ,so you can install it via #Synaptic Package Manager -->search for wvdial

---OR--
Insert original Ubuntu Cd

Go to System->Administration->software sources. add cd as a source and close . It will update itself, Then on terminal type,

sudo apt-get install wvdial .

2) Type lsusb command and see what it gives (for me below was result)


binnishah@google:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 045e:00a4 Microsoft Corp.
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 005: ID 12d1:1411 Huawei Technologies Co., Ltd. ---------> ( Model #,vendor# & product# to trace for modprobe just in case your OS can't catch it plug n play)
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


3)I have Huawei Mobile connect whose model # is EC121 and vendor = 12d1 & product=1411
next,

modprobe usbserial vendor=0xAAAA product=0xBBBB ,

Where AAAA is 12d1 and BBBB is 1411 in my case.

4)Open terminal and give command ( pl.give these while inserting USB photon drive in lap/Server)

sudo wvdialconf /etc/wvdial.conf ---> (These will detect the modem and install it for internet connection by inserting appropriate modem configuration into /etc/wvdial.conf)

** Pl.dont forget sudo or else you will be trapped into permission issues of /usr/sbin/pppd & chap-secrets & pap-secrets permissions and worse would be wvdial.conf wont get Baud speed rate self detected ,neither exact location of modem would be traced

5) Open wvdial.conf in /etc with :-

sudo vi /etc/wvdial.conf ,it has some entries by default add some new & match it as belows:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CRM=1
Stupid Mode = 1
New PPPD = Yes
Modem Type = USB Modem
Phone = #777
ISDN = 0
Password = internet ---> Your ph number of tata/password
Username = internet --> Your uname /#
Modem = /dev/ttyUSB0
Baud = 9600 -->Baud rate would be decided by 4rth command and written automatically into wvdial.conf script

Now save & exit vi,

6)type sudo wvdial

It may give you something like these:--

binnishah@google:~$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

OK
--> Modem initialized.
--> Sending: ATDT#777
--> Waiting for carrier.
ATDT#777

^CCaught signal 2: Attempting to exit gracefully...
--> Terminating on signal 15
--> Connect time 5.1 minutes.
--> Disconnecting at Sun Oct 18 17:52:50 2009

7)Command tail -f /var/log/messages --> Just immediately aft.connection gives following:

binnishah@google:~$ tail -f /var/log/messages
Oct 18 17:47:48 google pppd[13130]: Warning - ***

Oct 18 17:52:50 google pppd[13130]: Sent 158772 bytes, received 741237 bytes.

8)If you dont want to fall in hassles of pwd ( I wouldn't recommend to do so ,though)

sudo vi /etc/sudoers

# User privilege specification
username machine_name = NOPASSWD: /usr/bin/wvdial

So next time when you give wvdial you dont need to type in password


*For Fedora-11 - TATA Photon Whiz :- ==========================

It came to me as surprise that Fed-11 took it in plug n play ie:- just some tweak with Network manager applet and I was sorted out with live n kicking
tata photon whiz USB Mobile broadband

1)Open Network manager applet
2)In that,there's option of --> Mobile Broadband -->Add ( By default you will have Huawei Technologies or your preferable qualcom or whatever) -->Select it -->Forward -->Country - India -->Forward --> Select Tata Indicom(Plug2Surf) if you have photon whiz -->Forward ->Commit changes by pressing apply
3)In Popup of Editing tata Indicom
Add your username & password
and simply press apply
4)Left click Network manager applet and you will have option of Tata Plug2surf ,select it and you are all set

Hope that helps !!!

Determine Grade of steel

/*A certain grade of steel is graded according to the following conditions:
*1)Hardness must be greater than 50
*2)Carbon content must be less than 0.7
*3)Tensile strength must be greater than 5600
*
*The grades are as follows:
*
*Grade is 10 if all three conditions are met
*Grade is 9 if condition 1 & 2 are met
*Grade is 8 if condition 2 & 3 are met
*Grade is 7 if condition 1 & 3 are met
*Grade is 6 if only one condition is met
*Grade is 5 if none of the conditions are met
*
*Write a program which will require the user to give values of hardness,carbon content and tensile

*strength of the steel under consideration and output the grade of the steel*/

# Solution code :

==========

#include <stdio.h>
int main(void)
{
int hard,ts; // hard = hardness ; ts = tensile strength
float cc; //cc -- Carbon content

printf("\nEnter hardness of steel: ");
scanf("%d",&hard);

Determine if eligible for premium & Policy

/*An Insurance company follows rules to calculate premium

1)If a person's health is excellent and the person is btw. 25 & 35 years of age and lives in city and is a male then the premium is Rs 4 per thousand and his policy amount cannot exceed Rs 2 lakhs.

2)If a person satisfies all the above conditions except that the sex is female then the premium is Rs 3 per thousand and her policy amount cannot exceed Rs 1 lakh.

3)If a person's health is poor and the person is btw. 25-35 and lives in village and is male ,the premium is Rs 6 per thousand and his policy cannot exceed Rs 10,000

4)In all other cases the person is not insured

Write a program to output whether the person should be insured or not ,his/her premium rate and maximum amount for which he/she can be insured.*/

Determine character input if its Capital,small,decimal or special character

/*Any character is entered through the keyboard ,write a program to determine whether the character entered is a capital letter,a small case letter,a digit or a special symbol

Following is Range of Ascii values for various characters:-

Calculate gross salary

/*If his basic salary is less than Rs. 1500, then HRA = 10% of basic
salary and DA = 90% of basic salary. If his salary is either equal to
or above Rs. 1500, then HRA = Rs. 500 and DA = 98% of basic
salary. If the employee's salary is input through the keyboard write
a program to find his gross salary.*/

Solution Code:-
=========

Print a five digit number by adding one to each of its digits

/*If a five-digit number is input through the keyboard, write a
program to print a new number by adding one to each of its
digits. For example if the number that is input is 12391 then
the output should be displayed as 23402.*/

Calculate price of single item

*If the total selling price of 15 items and the total profit earned
on them is input through the keyboard, write a program to
find the cost price of one item.*/

/*Here the query maker ,I suppose seeks for groce price rate of one item ,as groce profit & groce selling price is sought out
sin => single item groce price ; procin => profit on single item ;con => conjugal price (profit + single item price)
