x I have a program which insists on having a tty as its standard input. It is a commercial, binary-only program, so I can't tell you why, but presumably it is doing stty's or something. I want to drive it from a prepared script. Any ideas ? Seems to me one could write a program which builds a pseudo-tty between itself and the binary program in the manner of a pipe and feed it from a file or whatever. However this is probably a bit of work. Anyone written such a thing ? Any other ideas ? Using 4.2BSD script does not work, but perhaps it could be hacked to work... Cheers, Dan Ts'o Dept.

Does anyone have a nice package that allows you to say something
like
process("silly_game arg1 arg2",&input_fd,&output_fd,&error_fd)
and start the process running not on a pipe (I have one of these) but
rather on a pty so that the proc can 1) do ioctls 2) have line buffered
output ?
thanks,
