I remember this place being very helpful a few years ago, so this is the first place I thought of when I ran into this problem.

I'm doing independent study this semester (actually a third one-month semester; my university is a bit weird). The professor that I'm working with requires exactly what I've stated in the title. I know it's possible; I've seen AJAX terminal emulators, but I don't need something that complex. I'm pretty fluent in PHP, javascript, and the AJAX technique, but I'm really unsure where to start here. I know that, short of writing a terminal emulator, I need to find some way to redirect I/O to the browser, but I don't think piping is the answer.

Perhaps the best example of this I can think of is here. They sort of trick the browser into thinking that the page never fully loads, which allows instantaneous response to commands via AJAX.

I know that this is complex, but I would appreciate even a nudge in the right direction. It doesn't matter if this is done "right" or "well." My professor requires a quick-and-dirty solution, if you will.

Thanks in advance.
