    Hi all,
    I'm trying to run a COM.Open FB in a Codesys 3.5 runtime of a Linux Embedded Device (Topcon OpusA3).
    I've got a look at serial sample on 3S website, but if I run the COM.Open I always get ERROR_UNKNOWN. Every suggestion is highly appreciated!

    You should check your ParemetersList array.
