    Verified purchase
    Worked finally great, but I was lacking the pinout of the 9P DB RS232 connector (cant be found online or in ebay listing), and believe it should be a MALE instead of FEMALE connector (PC's have MALE, this is not a PC, therefore it should be FEMALE). Further, the TxD and RxD seems to be flipped, as using a regular tested RS-232 standard cable between the relay and pc / amiga did not work until i flipped those pins. Once all of that, it worked as described per. documentation of BITS and BYTES.
