I GET device unavailable error when opening com1 or com2. I have entered the com ports setup in the ini file, both as PORT:com1 PORT:0 But they still return DEVICE UNAVAILABLE error i am using WINDOWS 7 64 BIT.

Do you have a physical serial port? They are very rare on modern computers.
If it's a USB serial port, these are usually not at the Windows address COM1 but some higher number (e.g. COM20 is often used). You'll need to find out the address of the port in Windows first and confirm it is working in Windows.
If you then still have problems, please attach your INI file and the program or statement you are using to connect. It would also help to give some more information about what you are trying to do, as serial connections are difficult due to the many places where things can go wrong.
