Hello Steen >I am right now working on a serial RS-232 line with my PIC. I think my code >works fine, I just need a tool for testing it. 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. I have been using a small program for a long time. It is just 14K size and runs under DOS. You just invoke it with com port number and baudrate (Ej: START 2 9600 for COM2 9600bps). I'm sending you the program directly. If anyone in the list is interested just drop me a message directly and will answer back with the START.EXE attached. Regards Luis Fernandez Cormenzana RadioBit Sistemas, S.L.
