Thank you very much for your quick response. I’m sorry you had to buy the cable to make the connection. I’ve seen that cable, and it looks like a normal female-to-female serial cable, though I’m not sure if it's crossed or pin-to-pin. But it must do something for it to work for you. I have made significant progress using a conversion table between bytes and expected ASCII. So far, it works for me, but I don’t know if it will change between different devices or if I stop using the serial cable with the USB adapter. Here’s my conversion table:
conversion_dict_hex = { '0x6': '0', '0x67': '1', '0x33': '2', '0x66': '3', '0x19': '4', '0x65': '5', '0x32': '6', '0x64': '7', '0xc': '8', '0x63': '9', '0x69': 'x', '0x56': 'S', '0x58': 'O', '0x4': 'p', '0xb': 'H', '0x2b': 'R', '0x3': ' ', '0x35': '*', '0x61': '=' }
