Hi Dan, You already said, "I can get it to look alright if I select "add cr/lf at end of line" within Hyperterminal". Instead of fighting HyperTerm right now, why not just create a HyperTerm session file (.ht) with the settings that you already found to work and give this to your customers? They would then load this session file. Would this be a viable solution for you and your customers? This would seem to be the cheapest and quickest interim solution for you if you have to use HyperTerminal. If you have the time later, you can always go back and keep experimenting with HyperTerm.
