    DG41MJ serial port header incorrectly configured?

      I've been trying to get the serial port working on my DG41MJ motherboard. It's enabled in the bios, and connected to the back panel by a straight through serial adaptor cable (10pin header to 9pin rs232). After not much luck I eventually got round to comparing the output current at the pins with an older working machine and noticed a difference.

      On my DG41MJ I get a current between pin2 (RxD) and pin5 (ground) however on my older machine I get a current between pin3 (TxD) and pin5 (ground).

       

      Does anybody know why this is? I'm assuming this is why I can't get any of my serial peripherals to work if the input and output channels are inverted.

       

      Is there a solution?
