On the new version of M2M studio conection over serial port with the Fastrack gives problems:  
[_]I switch on the Fastrack, send AT and get response.  
[_]I changed to the OpenAT perspective, and select RTE\_Debug on Debug on the tools bar.  
[_]It start and few seconds after it gives an error: Target no connected.  
[_]I go back to the Target Mang. perspective, and get no response to AT.  
[_]I disconnet, open an hyperterminal on the serial port and repeat the AT sending. Now it works 😮  
[_]If close and open the port on Selima, it also works. ❗

What’s going on??? Anyone has the same problem? ☹
