Connecting to Ultra 10 Serial Port B with Keyboard/Video also connected
Hello-
I know that powering up an Ultra 10 with a keyboard/monitor attached will prevent the serial port from activating.
I am testing both IP-enabled KVMs and serial consoles, so I would really like to access the machine using a KVM and the Serial Port, but I cannot figure out how to activate the serial port after booting with a keyboad/monitor attached to my Ultra 10.
Any ideas?

You can't, there is only a single console: Either serial or keyboard/monitor.

There is a nice Sun doc that explains how to set this up by changing input-device and output-device to ttya and modifying your dt config and logindevperm.
Keywords: dtlocal logindevperm
Note: You will no longer be able to login at the Monitor/keyboard directly as root (Not on console)....only the ttya port.
