We have a 2-port esl that has been working fine with 3 different computers sharing the 2 ports. The ports are connected to scale indicators that send continuous streams of weight data to our software. Today, while installing a new software package to read the scales we were having issues with unexpected characters in the data string (ascii 63). Then, the port that was exhibiting that issue stopped communicating completely. We can no longer access that port in hyper terminal, although the other port is working fine. I have tried deactivating and reactivating the port and rebooting the computer. The esl web page shows both ports are inactive. The other 2 computers are having no issue connecting to both ports on the esl. This has been working without any issue since 2014. The o/s is Windows 7 pro.
