Instrument Control (GPIB, Serial, VISA, IVI)
overrun error when using multiple serial ports
Hi
I edited the subvi, the only real action is the addition of the error clusters.
To make sure that your main program can handle the error instead of popping up an error dialog.
To read the number of bytes available see inside.
I now read the rest of the buffer and throw it away. (even faster when no indicator is present)

Hi
This can happen because of reading all that is left and then waiting for a new set.
You should be able to synchronise if you know exactly how each message is built up.
The best would be to use an end character as cr or lf if the controller sends that.
If you like I can take a look.
The only thing you need to do is send me a long list of consecutive characters read in one string.
the best you can do is read e.g. 100 characters and display this in a vi.
then make current values default and send it to the board.

Here is a version 7.0 with still the same behaviour.
first reading 17 charcters, then reading the rest of the buffer and maybe part of the next wanted 17 characters.
But if you could find out that there sometimes is a weird reading why do you need this vi in 7.0?
