I don't know what "IPMI Console" is if it's not SoL. Specifically, we
use ipmitool -I lanplus ... sol activate. We emphatically never use
anything associated with the Supermicro web UI, with a single exception:
it's useful in the lab only for one-time testing of BMC firmware
upgrades. After that it's always FDUM, which unfortunately is not part
of SmartOS due to third-party licensing restrictions. The open source
parts are in sdcboot.

Ok. You're off the golden path, then. Maybe call Supermicro
(*snicker*).

Clone sdcboot and type gmake? You will need to fork (or just modify)
the ipxe repo though, to change the serial port.

It's intended to build on SmartOS. There is no way to build any of our
repos on a mac. Don't be fooled by makefile cruft that refers to
Darwin; I've removed that stuff in the past but others keep adding it
back because they insist on running 'gmake check' on their macs. You
can't actually do anything useful there.

The options passed via -B need to be comma-separated. You are losing
your console setting because it is not part of the comma-separated block
following -B. That's why you don't see output on the serial port after
booting.

Yes.

Do not specify redirection after POST. On most firmware that confuses
everything. The only software that should be using firmware-based
redirection is the firmware. ipxe and everything after know how to use
the serial port directly.
