There's no ANSI standard graphics library. I assume you meant a ASCII UI,
but you might also mean one of the early graphics libraries provided by
compilers, like the Borland Graphics Interface (graphics.h in Turbo C). If
it's ASCII graphics, the ncurses library will do what you want. If it's
polygon graphics, SDL will work fine (also great for handling user input).

You'd probably have to ditch that and use something more modern like
pthreads (All hail RMS, deliverer of POSIX).

Again, POSIX saves the day. Opening a serial port using C on a GNU/Linux
environment is criminally simple. We're talking `int fd =
open("/dev/ttyS0", O_RDWR | O_NOCTTY | O_NDELAY);` simple.
