Has anyone written a routine to open a pipe to a process which
requires that its input come from a tty? I think the fakeout
involves pseudo-terminals, but I don't know much about them and
would just as soon use someone else's code if it exists.
To be slightly more specific, I'm trying to run tip from perl
on a Sun4. Being able to do something like
ptyopen(TIP,"|/usr/bin/tip portb");
would be wonderful, but even if you have it in less elegant form
I would love to see your code.

The first quick answer is use PTY's. People have posted code here from time to time to use them. The slow answer is, if you hold on about a week or two, you may be pleased by some code that Larry and I have been working on.
