TCPIP to serial port in xp

    Question

  • I have an XP industrial advantech computer with six comm ports. I load my ethernet control SW to this device and nothing transmits The error/activity log shows that com 3 is opened and the data to send is received over the ethernet and put in a buffer to send. It then says the write API will not open and eventually it kills the port.

    This SW runs on a laptop (XP) without errors but not on the ARK.

    What do I need to do to  check that the socket is working properly and that the send API will run.  I get the impression that the RX side is working but cannot prove it without the TX operation.

    It is something simple I am sure with XP, as I have seen this SW run on all sorts of XP machines without problems.

    Any thoughts would be helpful
