I don't run SSH 2 because I don't like the license for it, I'm basing all of this on
1.2.27.

I'd put one of my debuging messages after this line here

and here. Little gems like this:
log_msg("%s:%d tcgetattr 1 -failed %d %s (%s)\n",
__FILE__, __LINE__, fd, strerror(errno),
Also look for where it's doing
isatty(...)
and instrument those as well. Then try pushing "ptem" & "ldterm" just before
the one that is failing (make it a tty). Hmmm, actually you know where it is failing

It's right here.
Hmmmm, I might be steering you wrong with this. It's not that your tty isn't
configured
correctly, it's that you don't have a tty. You could try opening /dev/null in this
case
and pushing the modules on to that file descriptor? Pretty gross but, ...
