When Agent Smith, or another goon of the agents, uses his earpiece and then begins to tap into a "blue-pill" human, taking over his entity, what language are they hearing?
They're sentient programs, not fax machines. Though I wouldn't be surprised if the canon somewhere states that the messages they're receiving through their ears sounds just like a fax machine.
Or is it visual?
Basically, in The Matrix, how do agents communicate with each other? And on top of this, who are they getting the information from?
