Check out the patches for Emacs 18.55 available on afsg.apple.com. I've been using those for some time with no problems on handling subprocesses on ttys. Alas, I don't know exactly what the problem was, but Ron Flax at afsg.apple.com fixed it. (As I recall, the patches for Emacs on apple.com had other problems as well, which were all solved by going to the Ron Flax-patched version.) >example of bug: > M-x shell >does not work.

Well, it looks like the shell is still created with controlling tty as '?', but the shell prompt appears as normal, and interaction with the shell works just fine. I've got a shell running in the other window right now as I write this. -- Richard Todd rmtodd@uokmax.ecn.uoknor.edu rmtodd@chinet.chi.il.us rmtodd@servalan.uucp "Try looking in the Yellow Pages under 'Psychotics'." -- Michael Santana
