To answer your questions. I assume the low-level console is working if it is showing up the dmesg output. Is there any other way to verify this? I appears that yes at this point the failure is occurring when getty should be taking over, is there way to verify this as well? I can indeed login to the Sun from the Dell using tip and cu, I have not tried minicom simply because cu worked before. I will try tonight to remove all serial cables, reboot both boxes without any serial cables attached, then I will just attach the Sun to Dell setup and try again. This is the only output I have from /var/log/aculog.
