Check if Arduino is connected to Processing

leoz67

Hi, I'm new here. I have a problem with arduino and processing. My scope is to know if arduino is connected or not, but I don't know how I can do that. I try to use setDTR, but I don't find any changes, messages or actions. I find notifyAll and notify functions, but I don't know how I have to use them. I'm very sorry for my english: I'm an Italian student and I'm learning english, but I'm not perfect. I'm waiting for a reply.

Thank you very much, but if I disconnect Arduino when the serial is opened processing doesn’t say: “Arduino Board is disconnected”: it continues working with a serial that is matched to nothing. How can I do to show to processing that the Arduino is disconnected? By the way the class Serial Connection is great and I want to use this class for my project.

Resolved. I'll adjust the code and then I'll post the code.
