Hi Matt,

I don't recall that problem. If it existed it would almost certainly have been in asynPortDriver (part of asyn) and not in areaDetector itself. I was using IDL to set waveform strings almost from the start of areaDetector and it worked.

The one problem I do recall was quite recent and had to do with clients getting callbacks with such arrays which were not null terminated because they specified a length. I recently changed asyn so that it includes the null terminator in the callback and in the byte count. As I recall camonitor was such a client but it was also fixed by Ralph Lange.
