Serial Port Problems RRS feed

  • Question

  • Hi, I am experiencing a strange problem reading data from serial ports on a Win 8.1 Embedded Industry Pro device.  I have tested using the Bray's Terminal app on a Surface Pro running Win 8.1 and on the device running Embedded and the Embedded device fails to read the incoming data stream properly.

    Does anyone have any insight in what might be different on Embedded version of Win 8.1 and whether this is a bug.  The application we are developing in using C#/WPF and has been working OK although we have experienced some intermittent issues with some serial devices.

    Our recent testing using Bray's Terminal seems to show that Win 8.1 Embedded has some issues when reading from COM ports.  We have tried using native COM ports on the motherboard as well as virtual COM ports using USB-RS232 converters but see the same issue with intermittent data coming through.  

    The same app seems to work fine on a Win 8.1 desktop with data coming through reliably.

    Any suggestions on where to begin with finding the problem would be welcome.

  • Do you get the same errors using HyperTerminal or Teraterm?
