I'm using an RFID reader connected to my computer over RS232 to usb port. It is using COM3 port with default settings (9600, 1 stopbit, no parity etc). After scanning a test card it gives me a nonesensical response, something like ··½w»··{íë
I think I tried almost all combinatios of baud rate, parity etc and I'm not getting a "normal" UID reponse. What could be a problem here? I don't know much about RFID and I can only assume that the test cards are ok. How can I find the correct settings? I contacted the supplier but I'm still waiting for a response.
Thanks :)
