# Below is a script that does this. It creates two pipes for communication
# between the Perl script and the external program, then forks and execs the
# external program with the pipes attached to STDIN/STDOUT. The perl script
# also creates the filehandles KEYBOARD and TERMINAL which do the obvious.
# You can then issue commands to the program via STDOUT, and read the responses
