Hello All,
What exactly is the Termination Character on the VISA Configure suppose to do. I ask this because it seems to behave different on different PC's.
I'm doing work with CCD buses where each message is terminated with a carriage return. So I initialize the com port with the term char for that. I was getting some odd behaviour some PC's, so I wrote a small vi that just reads the port and dumps the data into an array so I could see what each read was doing.
On some machines, it seemed to work fine, each cell in the array had a complete message with the char rtn, on others the messages are split between 2 or 3 cells, or are just not all there.
Is there something about the port hardware that ha
s to able to use the term char? The machines that seem to work OK are newer Pentium 3s, the others that don't work are older Pentium laptops around the 100-150MHz range. The one exception to this is our PXI-8156B's. They show the same problem. All of the ports are setup the same in the OS, which are a mix of Win95, NT4 and 2000.
Any Thoughts?
