Yep, definitely time to blow some dust off various old tomes :) Between 7.x and 8.x the default serial driver changed from sio to uart. You can recompile your kernel and get sio back and see if that has an = effect. Actually I see you used cuaU0 - that is a USB serial dongle so the = driver change would have no effect. That said the stack was rewritten between 7 & 8 too so perhaps that is = related. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --Apple-Mail-34-729272746--
