Telephone system works on the modem technology. There are different types of modems available. Any mobile available in the market is made up of a inbuilt modem and the controlling software. In market GSM and GPRS modems are also available. So keeping these things in consideration we are building a project to control the GSM modem which is connected to the system. We are connecting the GSM modem to the system using any supportable port like serial or USB port then develop software to control the functionality of the system.

3. Telephone system works on the modem technology. There are
different types of modems available. Any mobile available in the
market is made up of a inbuilt modem and the controlling software. In
market GSM and GPRS modems are also available. So keeping these
things in consideration we are building a project to control the GSM
modem which is connected to the system.
We are connecting the GSM modem to the system using any
supportable port like serial or USB port then develop software to
control the functionality of the system.
ABSTRACT

4.  To establish communication between two or more PC’s using
a GSM modem. The PC’s are not connected via internet or Wi-Fi or
Bluetooth or infrared in any way.
 Client-server structure, point – point communication between
the computers is also not used.
PROBLEM DEFINITION

5. Once user connects GSM modem to the system then user need
to pass predefined command to the modem so that modem can act
upon.
As we are developing the software any user can now connect
GSM modem to the system and can handle the functionality of his
laptop or the desktop directly by sending SMS from a remote
location. Even user can send the SMS from the system.
Now following are option which we are including in our project:
Remote PC Controlling
PC Security
Sending SMS From PC

9. PURPOSE OF USING VISUAL BASIC 6.0
The programming language forms the background of all
that takes place in a running VB program. VISUAL BASIC
programming language is an extension of QBASIC.
Much of rating a VB program requires placing graphics
object on the screen and setting attributes of those objects that
determine how the objects are to look and behave.
VB is an event driven programming language.

13. 1.GSM/GPRS delivers all the power of
instant wireless connectivity to your
multiple applications.
2. The modem is fully type approved so it can dramatically
speed up the time to market with a full range of Voice,
Data, Fax and SMS features (Optional TCP/IP)

14. HISTORY OF GSM
 In 1982, a consortium of European countries created the
Group Special Mobile (GSM) to develop a cellular technology .
 The European Telecommunications Standards Institute
(ETSI) took over the project in 1989 and finalized the first set of
technical specifications.

15. NETWORK STRUCTURE
The network
behind the GSM system
seen by the customer is
large and complicated in
order to provide all of the
services which are
required. It is divided into
a number of sections and
these are each covered in
separate articles.

16. ADVANTAGES OF GSM
* Ability to use repeaters which reduces the effect of noise from
signals.
* GSM covers virtually all parts of world so international roaming
is easy.
* GSM can be used from anywhere
* It is portable and easily available

19.  Parallel port is a simple and inexpensive tool for building
computer controlled devices and projects.

20. SNAP-SHOT OF SEND AND RECEIVE
MESSAGE

21. TO SELECT MEMORY AND TO CHOOSE
WHETHER MESSAGE SHOULD BE
DELETED OR SAVED

22. TO ADD MORE COMMANDS AND SPECIFY
THEIR PATHS

23. This screen appears when the
system is locked

24.  Shutdown, Restart System, logoff System by using mobile
phone
 Send message to mobile phone from PC
 Receive message in system send by mobile phone
 Remote PC controlling system

25. ADVANTAGES
1. Easy to working with PC
2. It will reduce the need of keyboard and mouse
3. Save the Time
4. Avoid the unauthorized use of system
5. It increase the working speed
6. It handles chatting process
7. System lock remotely
8. System operates from anywhere
9. Provide home security by handling system remotely
10. Easy to used

26. LIMITATION
•If network doesn’t exist then problem occur
•If MODEM not connected to the system then system can
not perform any operation on the basis of command
•Mobile number must be register and valid

27.  Remote System Handling
 It will be used in server controlling room
 It will be used in Lab
 It will be used in Net Café
 It will be used in College
 This project can be used for chatting purpose from PC and
Mobile.
 This project can be used for providing system lock remotely
 Use of this project for remotely handling PC from mobile
phone

28. 1.More controlling options can be provide.
2.Detail information can be send over mobile.
3.More security options can be provided.
4.Send and receive multimedia messages.
5.Can be used in other locking systems.
6.Other appliances can also be handled.
7.It can implement for handling home appliances.

29. CONCLUSION
After all the explanation we conclude that
• Our project works fine for small requirements
• It can be improved with more man power and time
Hence we can say that our project work is completed
with all the modules with very few ratios of problems
Our project is used for remote controlling a PC
through mobile phone and provide security from
unauthorized user. It shows the communication between PC
and registered mobile phone.
