I used it prior to moving on to AsyncPro. IIRC, occasionally it would just 
stop sending/receiving (with no error or exception thrown). So it would act 
as if there was nothing connected to the port.

Re: AsyncPro, it seems like setting the port affinity to "CPU 0-only" makes 
it hang less often. I think my next step would be to try this component:

Thankfully, I created a facade pattern, so plugging in a different COM port 
object should not be that difficult.

What's your beef with .NET? :)

By the way, which version of Delphi are you using? I'm using Delphi 7.
