The setup being: - Room "big closet" (where I sit) contains "mDesktop". - Room "small closet" contains machines "mTest" and "mControl". - Machines mControl and mTest have a serial "crossover" cable (null modem) connecting their /dev/ttyS0 (COM1) ports. - I am using 'ssh' from mDesktop to connect into mControl. - I've setup mTest to listen on it's serial port for a login with the line in its "/etc/inittab": S0:12345:respawn:/sbin/agetty -L 38400,19200,9600 ttyS0 linux I sent -HUP to init on mTest to signal rereading its inittab. mTest appears to be spawning "agetty" on ttyS0 as expected/desired. *** my problem(s): - How do I use mControl's ttyS0 port to connect to mTest? - What program do I use on mControl to connect me to mTest? Notes/thoughts: I remember doing this with 'cu' in the past, but I've never felt entirely comfortable with this due to a comment in the 'cu' manpage: BUGS "This program does not work very well" Is there a preferred alternative? I vaguely remember using some sort of 'call device' like 'cua0' in cu that corresponded to ttyS0 with an invocation like: cu -l /dev/cua0 I've tried the above and "cu -l /dev/ttyS0" and neither work: mDesktop > cu -l /dev/ttyS0 cu: open (/dev/ttyS0): No such device or address cu: /dev/ttyS0: Line in use mDesktop > cu -l /dev/cua0 cu: open (/dev/cua0): No such file or directory cu: /dev/cua0: Line in use ------ The different error messages, in some part, have to do with the fact that under the new udev-managed /dev directory "cua0" no longer exists. Don't even remember, offhand, what it's Major-Minor device numbers were, but don't think that would necessarily help since the numbers under udev are allocated differently. Also, there doesn't seem to be any "default" config files setup for uucp anymore (I think it had some commented-out line that, commented-in, enabled cua0, but it has been a while. Is there a better way to do this these days? I also need to know how to do this to be able to connect to local devices that provide a serial port for management (when managing them sans-network). Eventually, I'd like to be able to use the serial port as mTest's console (as it's not always convenient to find a 'head' to attach it to (esp. right now with the VGA-monitor in that room having died recently :-))...
