in case PDEV-WriteRecord contains strings in UPCASE letters reading the same object afterwards returns UPCASE letters

In case a WriteRecord (e.g. PDPortDataCheck, CheckPeers) contains a string in UPCASE letters (which is not allowed) reading out the object later on also returns the string in UPCASE letters.
Expected behavior: Convert the string to lowcase prior to store it internally and use this lowcase string for all upcoming actions.
