Make absolutely sure that there's nothing else of note in the room.
Examine the vent. Does it have screws or an emergency release?
You thoroughly scan the room to find anything further of note within it. After a short time, you wind up finding a small clip that holds the wires together. As it appears to only be there to keep the wires organized in one place, there shouldn't be anything wrong with removing it.
A closer look at the vents reveals that it does seem to be actually separate from the wall, it is just that it is so flush that it originally appeared as part of the wall. Due to the angle, you can't tell if there is a release on the lower side, but you believe you see hinges inside the top portion.
Punch the monitor.
You attempt to punch the monitor out of anger from finding nothing, and your fist goes right through it. To your surprise however, it doesn't go through it in the conventional 'break into the monitor' way, but instead goes through it like it isn't even there. It appears the monitor is a hologram that displays the input and results of what you put into it.
>run program:'Hello World!'
Calming yourself, you attempt to use the computer. You decide to start with a basic prompt to launch a 'Hello World' program, to determine a way to accept input.

It seems to work as intended.
>delete system 32
You attempt to use the command 'delete system 32'. You heard that makes computers go faster.
> User Input Required
> run program: 'Hello World!'

> System #32 cannot be deleted from this Terminal

Well, that was an unexpected result.
What next?
