How to send data over COM ports?

Hi!
I have one text file in this format.

from:xyz@abc.com
to:1234@xyz.com
A 100

from:shs@sd.com
to:1245@dfdf.com
B 200

Like this I have thousands of line of data.
Now I have an header and trailer for each message and I want to transfer each of this message as a complete packet over an COM2 port which is attached to an leased line.
Now I want to know how do u access a COM port and after successfull accessing how do I send messages over it. And also if I have to convert the data in binary how do I do it?

I am asumming that you are using A windows platform. If you are all you have to do is use CreateFile and WriteFile, to file COMX where x is the number of the com port you want to write to.
