  1. What you can do

This extension module defines a module named PTY, which contains following module fungtions:

getpty(command)
spawn(command)

   This function reserves a pty, executes command over the pty 
   and returns an array. The return value is an array with three
   elements. The first element in the array is for reading and the 
   second for writing. The third element is the process ID of the
   child process. If this function is called with an iterator block,
   the array is passed to the block as block parameters, and the
   function itself returns nil.

   When the child process is suspended or finished, an exception is
   raised.  If this function is called with an iterator block,
   exception is raised only within the block.  Child process
   monitor is terminated on block exit.

protect_signal
reset_signal

   These functions are obsolete in this version of pty.
