We used AsyncPro with Delphi for most of our applications up until recently, 
and it worked fine, but it has some serious problems -- it doesn't work well 
on processors with hyperthreading (most new PCs).

My advice to Tinu would be to use MS Visual Studio Express to write his 
application. You can still use C++, and they have a built-in COM port 
component.
