Hi Unni,

It may be that Windows Update has installed a broken Prolific driver, check the update logs to see if it has been changed, if so you could try rolling back the Prolific USB to serial port driver.

    Hi Unni,

    if the COM port number is correct then there may be an issue with
    the remaining settings like baud rate or handshaking.

    Also check that your FT-857 had it's port set to CAT mode and not
    ATU mode. Check your physical cable connections.

    To use Omni-Rig select "Settings->Radio->Rig" as "OmniRig RIg 1"
    (or 2 if your Omni-Rug server is set up for port two to connect to
    your FT-857).

    Dear Bill
    Thanks for the suggestions.  The com connections are perfect and
    use to check frequently for its numbers.  I feel the problem is
    something with Hamlib.
    Is there any way to connect through Omnirig to FT857 to try
    whether the problem is with Hamlib or not?

        Hi Unni,

        those errors imply that the COM port number has changed,
        perhaps due to a Windows update causing hardware devices to
        be re-scanned. Check that the COM port number for your CAT
        interface is correct by locating it in the Windows Device
        Manager application.

        Prolific USB to serial adapters do not store their COM port
        number and can potentially change just by re-scanning the
        hardware devices or by plugging into a different USB hub or
        hub port.
