I'm not sure it is get_pty(). All is seemingly okay when creating a zpty
command but trying to read from it (-r, -t, -L etc) just hangs till I
press Ctrl-C.

That results in exactly the same happening so isn't much help.
Could we perhaps try taking code from here:
http://cvs.sourceforge.net/viewcvs.py/expect/expect/pty_termios.c?rev=5.37
At the top, it says the file is in the public domain so we can use it.
It seems to indicate that we need to trap some ioctls. Also looks like
it uses /dev/ptym.
Is it worth trying to do something before 4.2?
Oliver
