Have you even _read_ the code of layer23 ... it _will_ not do what you
want directly. It's a starting point, but you're gonna have to learn
to write things by yourself.

Well it's a perfectly normal behavior that after some time you only
see lost frames.
I suggest you re-read the code and the specs until you understand
_why_ it's normal.

Not out of the box, as I said, you will need to do some programming.
Given the question you ask, you obviously don't understand GSM or the
code enough yet to do it.



PS: Please don't hijack a thread that has nothing to do with what
you're writing about by just clicking the reply button and not even
bothering to change the subject ... seems like you need to read the
emails RFC as well ...
