The response format is:
#SI: <connID>,<sent>,<received>,<buff_in>,<ack_waiting>
where:
<connID> Socket connection identifier.
<sent> Total amount (in bytes) of sent data since the last time the socket connection
identified by <connID> is opened.
<received> Total amount (in bytes) of received data since the last time the socket connection
identified by <connID> is opened.
<buff_in> Total amount (in bytes) of data just arrived through the socket connection
identified by <connID> and currently buffered, not yet read.
<ack_waiting> Total amount (in bytes) of sent and not yet acknowledged data since the last time
the socket connection identified by <connID> is opened.
Note: Not yet acknowledged data are available only for TCP connections; the
value <ack_waiting> is always 0 for UDP connections.
