I was able to do this in ~14 lines of expect. Can I do the same sort of thing with chat? This was under 1.1.5 when I fixed slattach so that it would work with an expect script. Dave is trying to do a similar thing. Some how, slattach was broken when it was brought into 2.0. I've known this for some time, but haven't had the time or need since I got a dedicated line to track it down. The tty code is not my area. It would be nice if someone who knows the tty code and slattach could look to see what is happening when expect is used with slattach. My fix for 1.1.5 was to restore the tty state from a snapshot taken during startup. The multiple forking nature of the current slattach makes this much for difficult, and it was a cludge anyway. -- Justin T.
