I have a large customer who, periodically loses keyboard functionality. As far as I can tell, the terminal completely stops receiving input, as none of the on screen buttons work, including the on-screen keyboard, as well as the physical keyboard. They report that the terminal is "freezing" but the cursor still follows touch on the screen.
Here is the odd part - When I remote into the "frozen" terminal, they keyboards start working again. I don't have to do anything, in fact the last two times, I have just initiated the remote and asked them if it was fixed. The answer was "Yes! What did you do?" Unplugging the keyboard and plugging it back in does not fix it. A reboot of the terminal does, but they just call me to remote in and fix it.
This site has 11 locations and 30 terminals total. Between all of these it happens to maybe 1 - 2 terminals per day. The problem is, when it happens on the server terminal, it takes down the whole store.
The terminals are running POS Ready 7 and RMS 2.0 with CU5. Anybody seen behavior like this in RMS or otherwise?
I am out of ideas. Thank you,
