R: Re: Problem with osmocon (beginner)

[screaming-pain at libero.it]

Thank you Sylvain and Dario!

It was a cable problem, I bought a usb one and It works, the only problem is 
that now I get a NACK,
I read it could be a timing problem and I tried to comment the printf as 
suggested in a recent post, but it did not work.

This is what happens:

Most of the times though it just arrives to the handle_write():finished prints 
out few  "got 1 bytes from modem, data looks like: " lines 
and it stops there

Do you have any suggestion? What should I check?

Thanks for your help,
Loretta
