Sorry if I didnot make myself clear. Hemscott is an ISP. I tried hyperterminal as you said but it loses the settings when you go back to DUN to try the ISP. Looking at the log file DUN sends an initialisation string that I guess is hardwired into the MS driver. What is annoying is that all the other ISP's work OK on this computer as does Hemscott on my other computer. Thanks for your help.
