Therefore: Do any of you have a small program for the PC (basic or something else) which will make me able to send single ASCII-codes via the COM-port to the PIC. I have tried to fix a basic program myself, but I am not very good a basic, so it will not work out the way I want it. Regards Steen Jensen Denmark >> If you are running Win3.1 you can use the Terminal Program or if using Win95 you can use Hyperterminal. We have used both of these for that purpose with great success.
