well, if you unplug the cable during transmission, then bytes might get lost... anyhow, the serial line is a little bit like UDP, as it doesn't have any built-in capabilities to check whether everything was transmitted. however, the main difference between UDP and the serial line is that since there are only 2 peers in the "network", you can guarantee that no 3rd party is causing digestion that might lead to data loss. so in practice, if you are using a a reliable physical medium (e.g. a cable that is not being tempered with), then you can assume that all bytes sent will also appear on the other side. so the only remaining question is whether both peers have spare cycles to actually handle all data that arrives. gmadsr IOhannes
