Question: Hsniffer is on the second serial port on the test box but it is not working. The program starts but it does not display any test messages and does not create an OUT file at the end of the test. I verified the hart modems are working and looked at the BIOS settings.

Sometimes the second serial port is not connected properly, or connected at all.  Please open a support ticket to request an RMA if you are currently enrolled in the Product Service Program.
