Hi,
I must read the serial port in one application and I would like to 
be able to change and select some options on my main window (which is a
dialog box). If I run (with a button) the function that reads the serial
port then there is no way to operate on the main dialog box due that the
process is busy on reading the serial port. 

I thought creating a MODELESS dialog box and launching from there the
function which reads the port I would overtake the problem, but it does
NOT do what I wanted. Again, I've got my main dialog box block until the
read finishes. 

I see two options now, one is trying to do the read as a non-overlapped
way, and the other is to use Threads (using TThread) I guess...

Could someone indicate if there is another way to solve this problem?
If the above two options are the most valid, could I have any good
example of using TThread ??

Thanks in advance,
Enrique BLANCO
