I have only just come across this issue - ignorance is bliss until caught out.
I also note that the Philips serials with DL#/AU# also have omitted characters.
E.g. Serial starting with AU1... actually on the monitor as AU1A...
Is there anything being looked at more recently for Lansweeper to automatically resolve these correctly?
