rudi Posted July 13, 2011 Share Posted July 13, 2011 Hi. Is there some function (or UDF) that can be used to reveal, which currently running process is using (=blocking) a certain COM port? If it's in the help file, I missed it... Regards, Rudi. Earth is flat, pigs can fly, and Nuclear Power is SAFE! Link to comment Share on other sites More sharing options...

guinness Posted July 14, 2011 Share Posted July 14, 2011 Currently I use Handle.exe to enumerate the list of open file handles, but it would be useful to have a Function.
