Enrico,
IF you have COM1 in your micro, could you try this code for a COM port that doesn't exist ?
I'm having the problem when I try to do an OpenComm( cPort, 1024, 10 ), for a COM port that doesn't exist in my computer. The function returns -1, but each time I try, CPU use is increased quickly.

I tried your sample, (my sample, actually ), and found no problems. The only think I've changed is COM1 instead of COM4.

Antonio,
I'm having a problem with this example. It's increasing CPU use every time the dialog is opened and when it's closed CPU Use is not released. So soon the CPU use arrives in 100%.
Do you know why?
