Problem is as follows:
Some data received has to be forwarded to a connected serial device.
I cannot wait for an answer from the device as this would block other tasks.
So, upon receiving the answer from the device, I do not know from which
connection
the original request came.
I suppose this problem can be solved by using tcp_active_pcbs and storing
the request info in the callback_arg argument.
I just wondered if this is the right way to do it.
