Hi I know that this is probably a pretty trivial question, but I just "inherited" a cluster of HPs, and I can't seem to find all the manuals. What I'm trying to do it to use the RS-232 port on a HP9000s340 to hook up a terminal to it. SAM is no good, because I don't having anything emulating an hp terminal, so my screen is all messed up. Thus, I'm trying to use /etc/mknod by hand to do this. Based on the pages on adding a terminal in the "HPUX System Administrator Manual", I'm supposed to create a character device with a major number of 1. (Something that puzzles me is that a "lsdev" command says that /dev/tty has a major number of 2.) Fiddling around, I made some guesses, but they were apparently all wrong... So my question is: What should be the minor number of that gosh darn RS-232 port? Points that might be useful in helping me: - I'm doing this on one of the diskless cnodes. - The four bit DIP switch just to the right of the RS-232 port is in the following position (from left to right) UP DOWN DOWN UP and has the label CONFIG underneath it. - I want to set up a 9600 baud line. I don't see how this is relevant to the question, but you never know! - in /dev, there are no ttynn files. I assume that this means I want to name my device /dev/tty00. I'd really appreciate any help that you folks might offer! Thanks alot, -Bo Adler adler@tybalt.caltech.edu ...!cit-vax!adler adler@citiago.bitnet -- B.

Try the following to use the internal RS-232 of a 9000/340: mknod /dev/ttyd00 c 1 0x090004 And add to /etc/inittab: 01:2:respawn:/etc/getty ttyd00 9600 And add to /etc/ttytype (when using a hp terminal): hp ttyd00 See getty (1M), gettydef (4) and inittab (4) for detailed information. Best regards, Rob
