as for the console, all you have to do is learn a bit of curses
programming. Curses (available under Linux as ncurses) is a set of
functions to handle several terminal capabilities, such as gotoxy()
(different name actually, but same concept) and the like. Programs that
use curses are very portable.

As for the serial port, I'm afraid this is the tricky bit. Under Linux
you can't access the hardware as easily as under DOS. See below.

yes. Go to
ftp://sunsite.unc.edu/pub/Linux/sunsite/docs/LDP/programmers-guide
and have a look around.

hope it helps. Good luck.
