DOS ain't dead

ANSI escapes for input (Developers)

I'm confused by this question.

Terminals needed a way to send codes for special keys over the wire. DOS computers were supposed to use the DOS keyboard interrupt to read keystrokes, or the lower-level BIOS interrupt routines. For special keys you have to use the BIOS routines, as DOS will just return ASCII codes.

When acting like a terminal, sure, those keystrokes have to be translated to whatever ASCII codes the host is expecting. But for local processing it doesn't make sense.

What are you trying to accomplish?
