Setting mysql port number in agile toolkit - atk4

Question

How do I set a port number for mysql connection in Agile Toolkit? The mysql in my local machine is running in a different port 3307, how should be my connection configuration look like?
I tried the following but it did not work,
$config['dsn']='mysql://atk:password#localhost:3307/atk';
I am getting the following error when I try a db test,
C:\xampp\htdocs\atk4.1.2\atk4\lib\DBlite/mysql.php:40 [2] mysql_pconnect() [function.mysql-pconnect]: [2002] No connection could be made because the target machine actively refused it. (trying to connect via tcp://localhost:3306)
