If you don't understand this application for CJ1, I don't see where an application with CQM1 is going to help you any. Short of the LEN$ instruction used in the CJ1 program, the CQM1 program should be identical. What is it you don't understand???

I understand a little bit, but the cqm1 haven't got the len$ function, is necessary to calculate the len of the string? I go to read the manual... thanks a lot¡

In short yes. As the function is not available in the CQM1, you will have to do that yourself and include the length in your transmission.
