strength, all you need is to convert them into benefits. In short, try to advertise yourself by converting your features

into strengths.Your answers can be : -1) I am a hard worker and because of this ability I can work for additional hours to accomplish

my tasks.I am commitment oriented and hence I always enjoy the trust and confidence of my team mates whichenables me to perform my duties very easily.

2) I am adaptable, so I can handle any type of people and situations and also bring out the best from them in spite ofconflicting situations or opinions. I am a quick learner, so I can any subject quickly and analyze my job and add

value to it as well as I can identify the problem and solve them faster and better.3) My strength is that I have very strong values and ethics and a very good eye for detail. I believe in strong

relationships and have a very supportive family and very good friends.4) Ive always been a great team player and therefore I can work efficiently to produce quality work in a teamenvironment.I can accomplish a large amount of work within a short period of time hence I get things done on time.

Difference between Smart Worker and Hard Worker:"A hard worker always do right things but a smartworker always put things right."- If you are interviewed for a managerial position or for an admission ina MBA College,

Your answer can be:Well, I believe I am good at planning and execution, and working with people. Ive always been goodat detailing all the steps too. Even in college, I used to spend time organizing my week and planning astrategy to tackle each class and assignment. I love working in a team environment where I try to usestrengths of each individual in a team and hence produce the best results.EVERYONE CLAIM THEY ARE HONEST, HARDWORKING, SMART AND SO ON.. BUT

WITH AN EXAMPLE IT IS MUCH MORE BELIEVABLE.Tell me on the basis on which strength shouldwe select you?As an individual, I am a package of all my strengths that I have stated to you and I strongly believe that ifyou have to select me, you have to do so forall my strengths put togetherand not for one strength inisolation. However if you still insist that you would like to select me for a specific strength than theprerogative is yours sirCan You Work well Under Pressure?The best answer to this question is Yes.Working well under pressure is a good strength to have. But saying yes is not enough; you need toexplain how you can handle pressure situation to bring the best out of it. Tell the interviewer that you workthe same with pressure and without pressure.

Your answers can be:1) Sir, I can handle pressure of work. Whenever there is pressure of work, we need to tackle it from themental and physical stand-point. Mental stand-point would mean being in a state of relaxation andcomposure so that I do not feel stressed out during the course of my work and from physical stand-point; Ialways prioritize myjobin their exact order of merit and importance so that I can dispose them off quicklyand effectively.2) I work well under pressure because I dont panic. I use the pressure to help me work more efficiently.I maintain self control and work as efficiently as possible. At times, I try to prioritize and plan as much as Ican.3) Working under pressure has always been a learning experience for me because it helps me grow. Ihave always worked well during deadline, and I always learned how to work more efficiently afterward.4) Well I believe I work the same if theres pressure or not. I try and take the emotional factors and workhard regardless of down time. I always prioritize and organize myworkand hence that gives me aPsychological advantage over pressure. At times whenever time becomes a constraint I put extra effort andtime to meet the deadline. So pressure has nothing to do with my work.SHORT TERM GOALS:My short term goal is to find a position where I can use the knowledge andstrength I have.

Introduction

In this article, I will give you an introduction on how to do serial port communication on .NET platform using C#.

The .NET framework version 2.0 (beta) provides features for serial communication. The framework providesSystem.IO.Ports namespace. The new framework provides classes with the ability to access the serial ports on a

computer, and to communicate with serial I/O devices. We will be using RS 232 C standard for communication

between PCs. In full duplex mode, here I am not going to use any handshaking or flow control, I will use null modemconnection for communication.

The Namespace

The System.IO.Ports namespace contains classes for controlling serial ports. The most important class is the

SerialPort class.

The SerialPort Class

SerialPort class provides a framework for synchronous and event-driven I/O, access to pin and break states, and

access to serial driver properties. It can be used to wrap Stream objects, allowing the serial port to be accessed byclasses that use streams. That is, SerialPort class represents a serial port resource.

Creating SerialPort Object

By creating an object of this type, we will be able to programmatically control all aspects of serial communication.

The methods ofSerialPort class that we will use are:

ReadLine(): Reads up to the NewLine value in the input buffer. If a New Line is not

found before timeout, this method returns a null value.

WriteLine(string): Writes the specified string and the New Line value to the output

buffer. The written output includes the New Line string.

Open(): Opens a new serial port connection.

Close(): Closes the port connection.

To create a SerialPort object, all we need to do is:

Collapse | Copy Code

//create a Serial Port object

SerialPort sp = new SerialPort ();

In all, there are seven public constructors for creating SerialPort. But I am using the parameter less constructor, the

constructor uses default property values. For example, the value ofDataBits defaults to 8, and StopBits defaults

to 1. The default communication port will be COM1.

The public properties ofSerialPort class that we will use are:

BaudRate: Gets or sets the serial baud rate.

StopBits: Gets or sets the standard number of stopbits per byte.

ReadTimeout: Gets or sets the number of milliseconds before a timeout occurs

when a read operation does not finish.
