Thanks for your assistance! Is this something a customer or their computer tech could do with your assistance? I assume they would need a terminal with a serial cable (Connector?) to communicate with the CPU.

Is this something that could be coached over the phone?

They are in Quanah, TX 79252, 2 1/2 hours north west of Dallas TX and that is the closest city. Witchita Falls, Texas is 1/2 an hour and Lawton, Oklahoma is about an hour.
