Send GPS info over internet

I have GPS module which is working fine with arduino uno. I can connect with computer through USB and all the information I can able to see by using port COM9.

Now I want to send the information over the internet. I have GSM module and I can able to connect and send SMS about the location info.

My question is, how can I send the location [lat,long] information over the internet to COM9 port. So that my application can read the information and store it in the database.

Please advice on this.
