Here is my configuration for SuperMicro boards:

# loader.conf
console="comconsole vidconsole"

# /etc/ttys
ttyu1   "/usr/libexec/getty std.115200" vt100   on  secure

Depending on your Board the IPMI SoL is either COM2 oder COM3 by
default. My config snippets assume COM2 (0x2F8). If you board still has
two physical COM ports the IPMI SoL moves to COM3 (0x3E8) and ttyu2.
