A 'cu -l /dev/ttyu0' will "connect" me, however I get no prompt, and not input or output seems to be passed to the console port. All input gets dumped to the shell I executed the cu command from, *after* I kill the first (lowest pid) cu process. Example: yang# ps -ax | grep ttyu 687 ?? I 0:00.01 /usr/libexec/getty std.9600 ttyu1 688 u0 Is+ 0:00.01 /usr/libexec/getty std.9600 ttyu0 741 p0 R+ 0:00.01 grep ttyu yang# cu -l /dev/ttyu1 -s 9600 Connected *hit enter a few times, type hello john, then kill the first cu process from another shell* yang# yang# yang# yang# yang# yang# yang# hello john hello: Command not found. yang# Reading the handbook section on serial communications again, I don't see anything wrong. I'll be the first to admit this type of stuff is uncharted territory for me. If I skipped some required reading on the subject, please don't hesitate to point me to it. Regards, aaron.glenn
