However, in the present case where the keyboard port is bog-standard serial and is not in any way integrated with other display hardware (VGA chip), but rather lives alongside with other serial ports on the machine doing other things, it makes much more sense for the Linux kernel to treat it as a regular serial port without any LK201 knowledge and concentrate the latter in the X server. Of course I may change my mind once I get down into the code, but this is my current tentative plan. Me neither. But if I'm going to invest time and money into building my own hardware, I may as well do my absolute best job while I'm at it: it'll cost the same to make this thing with or without the additional port, and having more options supported for the same cost means a greater return on the same initial investment.
