Yup. I found a pty.c in the NCP system, it's clearly the ancestor (comments match): https://minnie.tuhs.org//cgi-bin/utree.pl?file=SRI-NOSC/dmr/pty.c > I suspect BBN got it from the Bruce Borden's Rand distribution tape Or possibly indirectly; my copy of the NCP came from NOSC via SRI. In addition to the one above, there are also these: https://minnie.tuhs.org//cgi-bin/utree.pl?file=SRI-NOSC/dmr/misc/pty.c.ill https://minnie.tuhs.org//cgi-bin/utree.pl?file=SRI-NOSC/dmr/misc/pty.c.x Here: https://minnie.tuhs.org//cgi-bin/utree.pl?file=BBN-V6/dmr/pty.c is the BBN version, you can compare the them all. The MIT one is derived from the BBN one. > Named Piped were definiately a Rand-ism (they were originally called 'Rand Pipes') Well, _RAND_ called them 'ports': https://minnie.tuhs.org//cgi-bin/utree.pl?file=BBN-V6/doc/ipc/ports > But there were issues and somethings were not 100% until the UofI NCP; > which was the first really complete NCP for UNIX. Somewhere I found a document about the UofI code, I think they wrote it from scratch? Sorry, too lazy to look at it. See here: https://minnie.tuhs.org//cgi-bin/utree.pl?file=SRI-NOSC for links. Noel
