COM ports don't have any automagic. If You want write some data to COM port and read this same data from this same port You must use loopback connector on this port ie. like this.

Yes, of course I did the loopback but i dont know if i have to configure and open the COM1 port in both programmes. I have tried both things but if it is opened in one program and then i configure the same port in another program to send datas to the other is telling that the port is close althoug i didnt close it.
I dont know well which is the process.

Of course You must open COM port in both programs in shared mode. Another solution is to use some application creating virtual ports makes connections betwen them. Than You can use in one program ie. COM5 and in second COM6.
