Usually, the OS can be asked, how much data is waiting in the out-queue to be delivered. So you can check, if all data made it to the destination and were ACKed -- the queue would be empty. So, it is more work to check it, but it can be done. -- Anything is possible, unless it's not. Michal 'vorner' Vaner
