Read serial data and detect serial break at the same time

[britehappy]

I need to communicate with a device via serial that sends messages back and forth but also sends a serial break/pause/break/pause combo that I need to listen for. I have never worked with serial breaks before but the only VI I found that appears to detect them is the VISA Wait on Event VI with the Serial Break parameter. I'm not sure I understand how I could detect a serial break but also be reading and writing messages at the same time while waiting. Is this not possible?

If you use multiple loops, I think you can do this.  You use 1 loop for checking to see if there is data and 1 loop for looking for the serial breaks.  You then use a queues, notifiers, or events to let whoever needs to know what you encountered.

I've not tried this, but the VISA Palette has Events, one of which is Serial Break, so you could "trap" these in an Event loop ...

Ok. I will try using multiple loops. I did not think I would be able to read from and wait on the same serial resource in separate loops, but I'll give it a shot!
