Problem Reading Data From The Hyperterminal

Projects General Guidance
1

I am trying to build a standalone arduino. And for serial communication i intend to use RS232 DB9 connectors as described in the example of this site -- http://arduino.cc/hu/Tutorial/ArduinoSoftwareRS232

But I am confused at how i read the data in the hyperterminal. While making a new connection in the hyperterminal which COM port should i use to make the connection to the DB9 connector and recieve the data from the Arduino into my pc?

You have to know the com port number assigned by windows to arduino.

Do this,

  • Plug out ur arduino
    Start hyper term (HT) and not down all the listed com ports.
    close HT
    plug in your arduino
    open HT again
    Now connect to the com port that wasnt there before.

Well as you will be using a DB-9 RS-232 interface you must plug it into a matching hardware DB-9 comm port connector on your PC. Your PC device manager software should be able to tell you the comm port number of your physical DB-9 connector. My PC has two RS-232 ports and are called com1 and com2. Once you figure out what your com port number is, that is what you set hyperterminal to match and also match the baudrate speed that your arduino sketch is using.

Is it possible to use the NewSoftSerial Library with such an arrangment? If so what are the drawbacks between RS232 serial communication and Serial Communication over the USB?
