slattach always exited early because fd is not open in acquire_line().
Other (trivial) changes that I've been neglecting for some time:
- Turn off O_NONBLOCK so that `chat' doesn't need to worry about it
(`chat' actually does worry about it).
- Really set speeds POSIXly :-). cfsetspeed() isn't POSIX.
- Fix spelling error in comment.
- Gripe about bad programming of doing everything from signal handlers.
slattach should be written to do everything from the sigsuspend() loop,
but I don't want to do it :-).
From me:
Use .PATH to find uucplock.c
