Yeah, all that was OK- I was just calling VISA Clear after the first send, which had the unfortunate effect of changing the baud rate. I'm now able to get the serial number of the unit, and parse the "No transponder found" error that comes back every time I try and use it :/ But I know why that is and I'm on the way to fising it. -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/
