You could pick up my pty program, which does the job for you. (You
appear to be using a Sun. pty currently works on any BSD variant.)
``pty foo'' runs foo under a pseudo-terminal. There are a lot of
options; enclosed is the output of pty -H.

pty runs a program under a pseudo-terminal session.
pty -ACHUVW: print authorship notice, copyright notice, this notice,

  program [arg...]: run program under a pseudo-terminal
Options processed l to r. Capitals turn things off. Here + means default.
