how to write a serial port driver (UART 0) COM Port

Hi I am new to Device driver development and I have to write a
COM port (UART 0) driver for chip DM6443.
I need get started help on it.

I have questions like

1)do I have to create more then one DLL project on one will do

2) what functions do I have to define in it

Note:- I have been through DM6443 document.

1) download the wdk
2) get the kmdf serial sample (<ddk>\src\kmdf\serial)
3) rip out all of the 16550 UART related hw accesses, keep the queues and
IOCTl processing exactly the same
