Version 3.4 introduced a bug that prevented DMX client connections from working.
This was due to the AppData/Dmx/TerminationBytes registry key not processing the escaped string correctly. \r\n should be processed as 2 bytes, one Carriage Return and one Linefeed. Unfortunately the string was not un-escaped and the termination string was processed as 4 bytes, ‘\’, ‘r’, ‘\’, ‘n’.
Here is a Wikipedia article on Escape Characters for those who are interested.
Version 3.5 has been released to resolve this issue.
