#include <curses.h>
man ncurses

I'm not sure if it's ANSI (oh shoot, and it's not even C++), but
this is from the manpage:
"
       The  ncurses  routines  emulate  the curses(3X) library of
       System V Release 4 UNIX, and the XPG4 curses standard (XSI
       curses)  but the ncurses library is freely redistributable
       in source form.

Easy enough to do: create and use (at least) two windows:
the main top window (everything except the bottom line) and
one one-line window at the bottom. Position & write the date
in the 2nd window whenever you want.

Not having done any serial communications programs, I can't say
for sure, but if you grab the source code to minicom or seyon,
they should give you good hints.
