Thanks for the ideas Steve, I tried the one byte at a time method and it works a treat, the switch off time is 500 us, I'm now in the process of trying to make that time shorter. We normally use AsynchPro components but since thats now open source and the RTS line is controlled by Windows 2000 now and not the component the delay between the data transmission ending and the RTS line falling is just too long, up to 10 ms. With the legacy systems we have out there I need to try and mimic the Asynch component if I can. Thanks to all who responded. Joe
