How to listen if com-port is sending data?

Hi,

I want to implement a magnetic cardreader. The cardreader is connected to a comport.
How can I listen within my application if any data is through the com-port (send by the cardreader).
And how to limit the comports that are checked? (only one comport will be used).

After I captured the sending of data the application must be started and the numeric value that is send, must be saved/stored for later processing (searching in a database).

Please supply me with an example.

Regards,
Stef

If you have any budget for components, I have tried TMS Async 32 http://www.tmssoftware.com/ta32.htm

It works very well.
