LabVIEW
Create a custom error code when bytes at port is equal to zero
I am trying to create some custom error codes for my VI. One of
them that I want to create is when there is no data on the serial
line. I was trying to do this checking the number of bytes that
are read in from the serial port. If the number of bytes is equal
to zero, it would return an error to check the cable or to power on the
device (using the general error handler and creating my own codes).
The problem is that I cannot figure out how to flag the error. I was thinking I could use the Equal in the compare pallette to compart the bytes at port to zero. If it was true, then the error would be flagged, otherwise it would be ok. Is there a VI to do this or some way to add the value to the error cluster???

It's pretty simple to generate your own error. All you need is an error cluster constant as shown here,
and defining the error code. If you go to Tools>Advanced>Edit Error Codes, you can create your own codes that get reported just like the native LabVIEW ones.
