Ok-- so I've got a mystery on my hands.
I'm currently manually PXE installing via IPMI, working in the terminal, and throughout the process of watching the terminal display information regarding the installation, I keep seeing
^[OP being repeated over and over--like someone is sitting on the keyboard.
The closest I've gotten to discovering what key this could be is this question
However, I can find no documentation of what the
OP portion represents.
This happens on multiple devices I've used with different keyboards, so it is not a keyboard malfunction. It also does not occur on other machines running the same installers.
Any insight would be greatly appreciated!
EDIT: (expanding off of the accepted answer) Ok so extension on the mystery. I'm pretty sure these codes only return if the system does not know how to deal with the input. It only shows up at a random point during the installation--and when I try to hit the F1 key to force the ^[OP to show up, it does not (where the arrow keys will continue to show ^[[A, etc.) This would lead me to believe it is able to handle the F1 key somewhere within the boot (to be expected for a boot program). Any explanation on how this mystery location could be getting the character code to show up?
