OK, so the hardware is essentially working, that's good. Could you confirm exactly what you meant when you said: On Mon, Oct 23, 2023 at 11:37:10PM -0400, Morgan Aldridge wrote: > Unfortunately, regardless of what input is provided on the > terminal, getty(8) just sends a new login prompt. Do you mean that: 1. Any single keypress triggers a new login prompt, (as if you were pressing enter each time). or 2. You can successfully enter a username, which is echoed back but then pressing enter the system just presents you with another login prompt instead of accepting the username and asking for a password. I assumed it was '1', but just want to check before going any further.
