    Hello
    TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long.
    There may be other ways, but I would make a UNION with string/array of bytes.
    Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send
    (Elements [3] to [30]) then 252 would be in [31]

    (I've assumed the idata is always the same length)
