How to trick an application into thinking its stdout is a terminal, not a pipe

Question

I\'m trying to do the opposite of \"Detect if stdin is a terminal or pipe?\".

I\'m running an application that\'s changing its output format because it detects a pip

There's also a pty program included in the sample code of the book "Advanced Programming in the UNIX Environment, Second Edition"!

Here's how to compile pty on Mac OS X:

man 4 pty  #  pty -- pseudo terminal driver

open http://en.wikipedia.org/wiki/Pseudo_terminal

# Advanced Programming in the UNIX Environment, Second Edition
open http://www.apuebook.com

cd ~/Desktop

curl -L -O http://www.apuebook.com/src.tar.gz

tar -xzf src.tar.gz

cd apue.2e

wkdir="${HOME}/Desktop/apue.2e"

sed -E -i "" "s|^WKDIR=.*|WKDIR=${wkdir}|" ~/Desktop/apue.2e/Make.defines.macos

echo '#undef _POSIX_C_SOURCE' >> ~/Desktop/apue.2e/include/apue.h

str='#include   '
printf '%s\n' H 1i "$str" . wq | ed -s calld/loop.c

str='
#undef _POSIX_C_SOURCE
#include 
'
printf '%s\n' H 1i "$str" . wq | ed -s file/devrdev.c

str='
#include 
#include

printf '%s\n' H 1i "$str" . wq | ed -s termios/winch.c

make
