If you mean one process sending output to two different terminals, and
you are using System V 3.2 curses then check out the routines;

	SCREEN *newterm(type, outfd, infd)

which sets up curses for output to a new terminal, and

	SCREEN *set_term(new)

which makes curses switch to the new terminal.

The above solution supports terminals of different types.

p.s. it helps if people mention what operating system they are using,
a lot of BSD systems still do not provide System V curses functions
(however many proprietary BSD based systems now ship the latest System V
curses libraries).
