Thanks for your response!
I'm trying to get the first option working. Sending the escape command has worked. But then I get a problem with saving all the incoming data. I think the problem is that I never know how much data is comming back, so that I can save it in a sting and send it later back to the computer. I'm also not sure about when the INQUIRY has ended so that I can send again the escape command and send the data back.
Could you help me with those problems?
Thanks!
