Emulab FAQ: Testbed Operations: What about serial connections to the Admin MFS FreeBSD?
In the Admin Freebsd, the configuration used for the serial line connection is:
baud: 115200 data bits: 8 stop bits: 1 parity: none flow control: none
When loading the Admin Freebsd, unless you've setup the BIOS on the blade servers to redirect their output to the serial console (doubtful), the first output you'll see will be from the first stage PXE boot loader (our PXEboot program). This program figures out what the node is supposed to do (boot off one of the disk partitions, load a memory-based image (e.g. admin MFS), wait, etc.) and executes that action.
